Software tool turns everyday objects into animated, eye-catching displays—without electronics
Whether you’re an artist, advertising specialist, or just looking to spruce up your home, turning everyday objects into dynamic displays is a great way to make them more visually engaging. For example, you could turn a kids’ book into a handheld cartoon of sorts, making the reading experience more immersive and memorable for a child.
But now, thanks to MIT researchers, it’s also possible to make dynamic displays without using electronics, using barrier-grid animations (or scanimations), which use printed materials instead. This visual trick involves sliding a patterned sheet across an image to create the illusion of a moving image.
The secret of barrier-grid animations lies in its name: An overlay called a barrier (or grid) often resembling a picket fence moves across, rotates around, or tilts toward an image to reveal frames in an animated sequence. That underlying picture is a combination of each still, sliced and interwoven to present a different snapshot depending on the overlay’s position.
While tools exist to help artists create barrier-grid animations, they’re typically used to create barrier patterns that have straight lines. Building off of previous work in creating images that appear to move, researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a tool that allows users to explore more unconventional designs. From zigzags to circular patterns, the team’s “FabObscura” software turns unique concepts into printable scanimations, helping users add dynamic animations to things like pictures, toys, and decor.
MIT Department of Electrical Engineering and Computer Science (EECS) Ph.D. student and CSAIL researcher Ticha Sethapakdi, a lead author on a paper presenting FabObscura, says that the system is a one-size-fits-all tool for customizing barrier-grid animations. This versatility extends to unconventional, elaborate overlay designs, like pointed, angled lines to animate a picture you might put on your desk, or the swirling, hypnotic appearance of a radial pattern you could spin over an image placed on a coin or a Frisbee.
“Our system can turn a seemingly static, abstract image into an attention-catching animation,” says Sethapakdi. “The tool lowers the barrier to entry to creating these barrier-grid animations, while helping users express a variety of designs that would’ve been very time-consuming to explore by hand.”
Behind these novel scanimations is a key finding: Barrier patterns can be expressed as any continuous mathematical function—not just straight lines. Users can type these equations into a text box within the FabObscura program, and then see how it graphs out the shape and movement of a barrier pattern.
If you wanted a traditional horizontal pattern, you’d enter in a constant function, where the output is the same no matter the input, much like drawing a straight line across a graph. For a wavy design, you’d use a sine function, which is smooth and resembles a mountain range when plotted out. The system’s interface includes helpful examples of these equations to guide users toward their preferred pattern.
A simple interface for elaborate ideas
FabObscura works for all known types of barrier-grid animations, supporting a variety of user interactions. The system enables the creation of a display with an appearance that changes depending on your viewpoint. FabObscura also allows you to create displays that you can animate by sliding or rotating a barrier over an image.
To produce these designs, users can upload a folder of frames of an animation (perhaps a few stills of a horse running), or choose from a few preset sequences (like an eye blinking) and specify the angle your barrier will move. After previewing your design, you can fabricate the barrier and picture onto separate transparent sheets (or print the image on paper) using a standard 2D printer, such as an inkjet. Your image can then be placed and secured on flat, handheld items such as picture frames, phones, and books.
You can enter separate equations if you want two sequences on one surface, which the researchers call “nested animations.” Depending on how you move the barrier, you’ll see a different story being told. For example, CSAIL researchers created a car that rotates when you move its sheet vertically, but transforms into a spinning motorcycle when you slide the grid horizontally.
These customizations lead to unique household items, too. The researchers designed an interactive coaster that you can switch from displaying a “coffee” icon to symbols of a martini and a glass of water by pressing your fingers down on the edges of its surface. The team also spruced up a jar of sunflower seeds, producing a flower animation on the lid that blooms when twisted off.
Artists, including graphic designers and printmakers, could also use this tool to make dynamic pieces without needing to connect any wires. The tool saves them crucial time to explore creative, low-power designs, such as a clock with a mouse that runs along as it ticks. FabObscura could produce animated food packaging, or even reconfigurable signage for places like construction sites or stores that notify people when a particular area is closed or a machine isn’t working.
Keep it crisp
FabObscura’s barrier-grid creations do come with certain trade-offs. While nested animations are novel and more dynamic than a single-layer scanimation, their visual quality isn’t as strong. The researchers wrote design guidelines to address these challenges, recommending users upload fewer frames for nested animations to keep the interlaced image simple and stick to high-contrast images for a crisper presentation.
In the future, the researchers intend to expand what users can upload to FabObscura, like being able to drop in a video file that the program can then select the best frames from. This would lead to even more expressive barrier-grid animations.
FabObscura might also step into a new dimension: 3D. While the system is currently optimized for flat, handheld surfaces, CSAIL researchers are considering implementing their work into larger, more complex objects, possibly using 3D printers to fabricate even more elaborate illusions.
Sethapakdi wrote the paper with several CSAIL affiliates: Zhejiang University Ph.D. student and visiting researcher Mingming Li; MIT EECS Ph.D. student Maxine Perroni-Scharf; MIT postdoc Jiaji Li; MIT associate professors Arvind Satyanarayan and Justin Solomon; and senior author and MIT Associate Professor Stefanie Mueller, leader of the Human-Computer Interaction (HCI) Engineering Group at CSAIL. Their work will be presented at the ACM Symposium on User Interface Software and Technology (UIST) this month.

You don’t need a four-figure Swiss movement to know what time it is—or look good doing it. One of the most wonderful things about “budget” watches today (although it’s kinder, or more appropriate, to say “affordable”) is that brands have learned to take design cues from luxury timepieces while quietly getting very good at the fundamentals: reliable movements, thoughtful materials, and proportions that don’t scream “cheap.” Take a look at the Orient in WIRED’s selection below as a prime example.
It could easily be argued that we’re in a golden age of affordable horology (see our full guide here for definitive proof), where, if you choose wisely, $350 or less can buy everything from a desirable dress watch, or a high-end collaboration, and even a supremely capable and classically chic diver. Pieces that will see you right from sunken wreck to boardroom table. And let’s not forget the retro allure of digital watches right now, either, with the Shark Classic not only being one of our favorites here, but at $70, it’s also the most affordable.
Moreover, should you decide to bag more than a few (and who could blame you at these prices?), we’ve even got the perfect carry case picked out: Nanuk’s IP67 waterproof and dustproof NK-7 resin $175 910 Watch Case (pictured above) with patented PowerClaw latching system—ideal for securing any timepiece collection, be it bargain or big budget.
Be sure to check out our other wearable coverage, including the Best Budget Watches Under $1,000, Best Smartwatches, Best Fitness Trackers, and Best Smart Rings.
Same as the Five Senses deck above, this scratch-off card set happens in sequence, with optional “level up” cards to really push intimacy, and separate cards for each partner with secret directions. For this date, you’ll both bring a red item that you show at certain points to signify that you’re open to physical touch. Then you’ll go out to dinner and have intentional conversation, and every time a partner pulls out the red item, you’ll follow the prompts to initiate increasingly intimate physical acts, ranging from hand holding to neck kisses. So there we were, at Illegal Taqueria, edging each other over al pastor tacos (I kid).
Many of the cards urged a partner not to interrupt or solve problems, but ask questions and talk dirty. My date said, “I think this may be for couples who hate each other.” I had to agree. The second part of the date involved driving and stoplights, but since we were in Brooklyn, we walked down the trash-filled sidewalk and pretended to be a suburban couple on the fritz instead.
The rest of the date included buying things for sexy time, like whipped cream and blindfolds. I’m vegan and had no desire to lick cream from chest hair, so we came home, stripped, and did our best to keep our eyes closed (in lieu of a blindfold). It was overall a strange experience for us both, I think. If you and your partner need a lot of prompting to connect, compliment, and be physical, this set is for you.
Date: Greg, 10/10 (Note: I didn’t find this man on Hinge; I met him the old-fashioned way, in a bar at 2 am.)
Box: 6/10
Valentine’s Day is a sneaky one. It’s easy to let grabbing fun and unique Valentine’s Day gifts fall to the wayside while you recover from the Christmas holidays, but it’s not one to miss if you have a partner you want to shower with a little extra love.
If you’re feeling too wiped to shop, good news: I’ve got you covered. I’ve rounded up some of our favorite ideas for the year’s most romantic holiday, from Lego sets you can build as a date and date boxes filled with ideas to last you all year long to gorgeous flowers you can get delivered in a snap and cozy robes you’ll want to lounge in together. This guide all the Valentine’s Day gifts we’re excited to give this year.

For a Gift That’s a Date
My husband and I are planning our fourth or fifth year of our favorite Valentine’s Day Date: building Lego sets together. We’ve done this for years, and then we get to enjoy the fruits (well, flowers) of our labor around the home forevermore. These sets serve as both the gift and the activity. Building the dried-flower centerpiece together was probably my all-time favorite, since you can each simultaneously work on one half and then click it together at the end, followed by each building a different-color bonsai tree.
For a Daytime Adventure
Retrospec
Weekender Crew Multi-Person Inflatable Paddle Board
Building on the idea of date activities that involve gifts, this multi-person paddleboard is a fun way to spend time outdoors while staying together the entire time. It’s massive, almost raftlike, so that it can support the weight of up to three adults, but once we got the hang of the size, it wasn’t hard to maneuver. Sometimes we’d both row together, sometimes I’d let my husband do all the work. It made for a lovely daytime adventure together, and I can’t wait for the next warm day for my husband and me to take this out on our local harbor again. It’s big enough that we could bring our son, though it’s much more peaceful as a date activity. It’s inflatable, and I’d recommend grabbing an electric filler since it takes a lot of manual pumping otherwise.
For Flowers on Demand

The classic go-to for Valentine’s Day is, of course, flowers. WIRED reviewer Boutayna Chokrane tested several flower delivery services to find the best one to get sent to your home, and her favorite is the Ode à la Rose, specifically the Edith arrangements. The business was created by two former French bankers, and the arrangements’ design choices feel distinctly chic in a way only French romance can. The Edith bouquet is entirely Columbus double tulips from Holland, and come hand-tied in a travel vase a fun pink box. The flowers ship nationwide, and there’s same-day shipping in New York, Chicago, Los Angeles, Austin, Miami, and Washington, DC.
For a Jewelry Upgrade
Maybe you’ve already exchanged rings, or maybe you’re looking for your first set without committing to I do. Either way, the most popular fitness tracker to get these days is a smart ring, and Oura is the ruler of the space. The latest model is the Ring 4, and it comes in both metallic and ceramic finishes. Many of my friends love theirs. I wish I had one, but they don’t make sense for my husband and me since we’re an aerialist and rock climber duo. Live my dreams for me and get this for your valentine (and yourself)!
For Your Fave Photographer
If your romantic partner loves to capture photos, a digital photo frame is the perfect gift (and you’ll benefit, too, as likely the number one fan of their photography!). I’m the photographer of our house, and our Aura frame is my husband’s favorite gadget because it showcases photos I’ve captured of our son and life together over the years. Our wedding photos can be found on there too, as well as the occasional good photo of me that he’s captured. It’s a monthly ritual for me to go through my camera roll and add my latest favorites. Aura’s my favorite because the range of frames is beautiful, and the storage is unlimited with no fees or subscriptions.
For the Cozy Couple
One of my favorite souvenirs I have around the house is a matching robe set that my husband and I bought on our honeymoon. Our all-cotton robes are from the Ten Thousand Waves Japanese spa in New Mexico (the final destination of a Southwestern US road trip) and are great for taking to the pool or using after a shower on a hot day. But I still love a good fluffy robe during the colder season, especially since it can double as a towel. Get your partner one of these cozy robes to give them something luxurious to use after their next everything shower or quick rinse-off. Cozy Earth’s robe is crazy-soft thanks to its blend of cotton and bamboo viscose, while this flannel robe from L.L.Bean is one of our favorites for anyone who works from home.
For Your Inner Theater Kids
If your partner loves to sing along to the Wicked soundtrack and is regularly suggesting karaoke as a group activity, then give them the gift of making karaoke happen anywhere with these gadgets. The Bonaok Karaoke Microphone is one of our favorite karaoke microphones, letting you sing anywhere without lugging bulky equipment. The Ikarao Shell S2 is a portable device with two mics, a built-in screen, and support for streaming services, so you can sing along to your favorite songs on Spotify.
For the Fitness Couple
After the Christmas season, I saw a video on my For You page that roasted how every mom had clearly gotten a matching workout outfit set for Christmas and was out wearing it on Boxing Day. As a mom myself, all I could think of was how much I would love another matching workout set. I’m serious. They’re great for workouts, quick errands, and day care or school drop-off. My latest favorite set is from Bombshell Sportswear. The set is both super soft and fits securely without any annoying squeezing. It’s getting the most compliments of all my sets. I wish I’d sized up with the bolero, but as an aerialist, my lat muscles are a little bulkier than an everyday person’s.
Have a partner who doesn’t need a matching set? Try some fantastic running shoes instead, which are even more useful for both workouts and daily life. WIRED reviewer Adrienne So says these R.A.D. shoes are fantastic for a range of uses, as they’re designed for gym, HIIT, CrossFit, and hybrid workouts and are soft enough for treadmill running. They look fantastic, too.
For the Beloved Bookworms
A Kindle is always a great gift for anyone who reads in any format. Funny enough, my siblings and I are about to buy one for my dad for his birthday (two weeks before Valentine’s Day), and I recommended my favorite pick, the Kindle Paperwhite, since the standard Kindle is a little too small for his 6-foot-4 frame to hunch down over, and he doesn’t read enough illustrated books to make the Colorsoft the right jump for him. If they already have a Kindle, I’m still in love with my matching PopSockets Kindle case and grip, and they’ve since launched a new Bookish collection with beautiful designs.
For Some Bedroom Spice
Looking to spice things up? These adventure boxes can add more fun to the bedroom without creating additional mental work for you and your partner. An offshoot from the Adventure Challenge, “The Adventure Challenge … In Bed” scratch-off date book has 50 date ideas designed specifically to help facilitate fun and connection in the bedroom. The dates are categorized by activity type in sections like food, dancing, “sexploration,” and more. Each date is covered by a black box, with only icons indicating required fields such as duration, cost, and more. Meanwhile, the Fantasy Box is a date-night box service offering a range of themes, from sexy wine tasting to a kinky poker night, all designed to help couples communicate and connect more intimately. Before opening the box, each partner will fill out a questionnaire of potential intimate acts, and this box comes with everything needed for a truly kinky night in: a satin blindfold, pleather paddle, lingerie, lube, massage gel, feather wand, mini vibrator, and silky wrist restraints. —Molly Higgins
