Prague’s City Center Sparkles, Buzzes, and Burns at the Signal Festival
And thanks to a mention in Dan Brown’s new novel, The Secret of Secrets, the festival has gained even more global recognition. Just a few weeks after the release of Brown’s new bestseller set in contemporary Prague, viewers were able to see for themselves what drew the popular writer to the festival, which is the largest Czech and Central European showcase of digital art. In one passage, the Signal Festival has a cameo appearance when the novel’s protagonist recalls attending an event at the 2024 edition.
“We’re happy about it,” festival director Martin Pošta says about the mention. “It’s a kind of recognition.” Not that the event needed promotion, even in one of the most anticipated novels of recent years. The organizers have yet to share the number of visitors to the festival this year, but the four-day event typically attracts half a million visitors.
On the final day, there was a long queue in front of the monumental installation Tristan’s Ascension by American video art pioneer Bill Viola before it opened for the evening, even though it was a ticketed event. In the Church of St. Salvator in the Convent of St. Agnes, visitors could watch a Christ-like figure rise upwards, streams of water defying gravity along with him, all projected on a huge screen.
The festival premiere took place on the Vltava River near the Dvořák Embankment. Taiwan’s Peppercorns Interactive Media Art presented a projection on a cloud of mist called Tzolk’in Light. While creators of other light installations have to deal with the challenges of buildings—their irregular surfaces, decorative details, and awkward cornices—projecting onto water droplets is a challenge of a different kind with artists having to give up control over the resulting image. The shape and depth of the Peppercorns’ work depended on the wind at any given moment, which determined how much of the scene was revealed to viewers and how much simply blown away. The reward, however, was an extraordinary 3D spectacle reminiscent of a hologram—something that can’t be achieved with video projections on static and flat buildings.
Another premiere event was a projection on the tower of the Old Town Hall, created for the festival by the Italian studio mammasONica. It transformed the 230-foot structure into a kaleidoscope of blue, green, red, and white surfaces. A short distance away, on Republic Square, Peppercorns had another installation. On a circular LED installation, they projected a work entitled Between Mountains and Seas, which recounted the history of Taiwan.

What Is That Mysterious Metallic Device US Chief Design Officer Joe Gebbia Is Using?
Joe Gebbia, cofounder of Airbnb and the US Chief Design Officer appointed by Trump, was spotted in San Francisco today using a mysterious metallic device. In a social media post on X viewed over 500,000 times, a man who looks like Gebbia sits with an espresso at a coffee shop. He’s wearing metallic buds that bisect his ears, with a matching clamshell-shaped disc in front of him on the counter.
After the video was posted Monday morning, social media users were quick to suggest that this could be some kind of prototype from OpenAI’s upcoming line of hardware devices designed in partnership with famed Apple designer Jony Ive. An OpenAI spokesperson declined to comment on the potential Gebbia video after WIRED reached out. Gebbia also did not respond to a request for comment.
The device Gebbia appears to be wearing looks quite similar to the hardware seen in a fake OpenAI ad that was widely circulated on Reddit and social media in February. That video from last month seemingly showed Pillion actor Alexander Skarsgård interacting with an AI device that had a similar-looking pair of earbuds and a circular disc. At the time, OpenAI denounced the widely seen video as not real. “Fake news,” wrote OpenAI President Greg Brockman at the time, responding to a social media post.
The earbuds seen in the video of Gebbia also look quite similar in shape to the Huawei FreeClip 2, a pair of open earbuds released earlier this year. However, the clamshell seen on the coffee counter next to Gebbia is different from Huawei’s most recent headphone case. It would also be quite surprising if a government official were seen using Huawei tech, considering the Chinese company is effectively banned from selling its phones in the US due to security concerns.
WIRED’s audio experts say he’s most likely wearing open earbuds, as Gebbia’s pair share some similarities with Soundcore’s AeroClips or Sony’s LinkBuds Clip, though the cases for those buds don’t match what’s on the table in front of Gebbia. WIRED also ran the photo and video through software that attempts to identify AI-generated outputs and other deepfakes. The detection software, from a company called Hive, says the odds are low that this imagery of Gebbia was generated by AI. Still, AI detectors are not always reliable and can include false outputs. It’s possible that the entire post could be a synthetic hoax.
Could this be some kind of soft launch teaser for OpenAI’s hardware? The timing of this trickle out would make sense, since the company may ship devices to consumers sometime early in 2027. Still, OpenAI denied any involvement with the previous pseudo-ad for the metallic AI hardware, with its shiny earbuds and matching disc.

The ‘European’ Jolla Phone Is an Anti-Big-Tech Smartphone
“There are Chinese components as well—we are totally open about it—but the key is that as we compile the software ourselves and install it in Finland, we protect the integrity of the product,” Pienimäki says.
What makes Sailfish OS unique over competitors like GrapheneOS or e/OS is that it’s not based on the Android Open Source Project, but Linux. That means it has no ties to Google—no need for the company to “deGoogle” the software; meaning there’s a greater sense of sovereignty over the software (and now the hardware). Still, it’s able to run Android apps, though the implementation isn’t perfect. Another common criticism is that it’s not as secure as options like GrapheneOS, where every app is sandboxed.
There’s a good chance some Android apps on Sailfish OS will run into issues, which is why in the startup wizard, the phone will ask if you want to install services like MicroG—open source software that can run Google services on devices that don’t have the Google Play Store, making it an easier on-ramp for folks coming from traditional smartphones without a technical background. You don’t even need to create a Sailfish OS account to use the Jolla Phone.
Jolla’s effort is hardly the first to push the anti-Big Tech narrative. A wave of other hardware and software companies offer a “deGoogled” experience, whether that’s Murena from France and its e/OS privacy-friendly operating system, or the Canadian GrapheneOS, which just announced a partnership with Motorola. At CES earlier this year, the Swiss company Punkt also teamed up with ApostrophyOS to deploy its software on the new MC03 smartphone. Jolla is following a broader European trend of reducing reliance on US companies, like how French officials ditched Zoom for French-made video conference software earlier this year.
The Phone
A common problem with these niche smartphones is that they inevitably end up costing a lot of money for the specs. Take the Light Phone III, for example, a fairly low-tech anti-smartphone that doesn’t enjoy the benefits of economies of scale, resulting in an outlandish $699 price. The Jolla Phone is in a similar boat, though the specs-to-value ratio is a little more respectable.
It’s powered by a midrange MediaTek Dimensity 7100 5G chip with 8 GB of RAM, 256 GB of storage, plus a microSD card slot and dual-SIM tray. There’s a 6.36-inch 1080p AMOLED screen, the two main cameras, and a 32-megapixel selfie shooter. The 5,500-mAh battery cell is fairly large considering the phone’s size, though the phone’s connectivity is a little dated, stuck with Wi-Fi 6 and Bluetooth 5.4.
Uniquely, the Jolla Phone brings back “The Other Half” functional rear covers from the original. These swappable back covers have pogo pins that interface with the phone, allowing people to create unique accessories like a second display on the back of the phone or even a keyboard attachment. There’s an Innovation Program where the community can cocreate functional covers together and 3D print them. And yes, a removable rear cover means the Jolla Phone’s battery is user-replaceable.

Engineering confidence to navigate uncertainty
Flying on Mars — or any other world — is an extraordinary challenge. An autonomous spacecraft, operating millions of miles from pilots or engineers who could intervene on Earth, must be able to navigate unfamiliar and changing environments, avoid obstacles, land on uncertain terrain, and make decisions entirely on its own. Every maneuver depends on careful perception, planning, and control systems that are fault-tolerant, allowing the craft to recover if something goes wrong. A single miscalculation can leave a multi-million dollar spacecraft face-down on the surface, ending the mission before it even begins.
“This problem is in no way solved, in industry or even in research settings,” says Nicholas Roy, the Jerome C. Hunsaker Professor in the MIT Department of Aeronautics and Astronautics (AeroAstro). “You’ve got to bring together a lot of pieces of code, software, and integrate multiple pieces of hardware. Putting those together is not trivial.”
Not trivial, but for students nearing the culmination of their Course 16 undergraduate careers, far from impossible. In class 16.85 Autonomy Capstone (Design and Testing of Autonomous Vehicles), students design, implement, deploy, and test a full software architecture for flying autonomous systems. These systems have wide-ranging applications, from urban air-mobility and reusable launch vehicles to extraterrestrial exploration. With robust autonomous technology, vehicles can operate far from home while engineers watch from mission control centers not too different from the high bay in AeroAstro’s Kresa Center for Autonomous Systems.
Roy and Jonathan How, Ford Professor of Engineering, developed the new course to build on the foundations of class 16.405 (Robotics: Science and Systems), which introduces students to working with complex robotic platforms and autonomous navigation through ground vehicles with pre-built software. 16.85 applies those same principles to flight, with a basic quadrotor drone and an entirely blank slate to build their own navigation systems. The vehicles are then tested on an obstacle course featuring dubious landing pads and uncertain terrain. Students work in large teams (for this first run, two teams of seven — the SLAMdunkers and the Spelunkers) designed to mirror real-world missions where coordination across roles is essential.
“The vehicles need to be able to differentiate between all these hidden risks that are in the mission and the environment that they’re in and still survive,” says How. “We really want the students to learn how to make a system that they have confidence in.”

Mission: Figure it out, together
“The specific mission we gave them this semester is to imagine that you are an aircraft of some kind, and you’ve got to go and explore the surface of an extraterrestrial body like Mars or the moon,” Roy explains. “You need to use onboard sensors to fly around and explore, build a map, identify interesting objects, and then land safely on what is probably not a flat surface, or not a perfectly horizontal surface.”
A mission of this magnitude is far too complex for any one engineer to tackle alone, but that too poses a challenge for a large team. “The hardest problems these days are coordination problems,” says Andrew Fishberg, a graduate student in the Aerospace Controls Laboratory and one of three teaching assistants (TAs) for the course. “To use the robotics term, a team of this size is something of a heterogeneous swarm. Not everyone has the same skill set, but everyone shows up with something to contribute, and managing that together is a challenge.”
The challenge asks students to apply multiple types of “systems thinking” to the task. Relationships, interdependencies, and feedback loops are critical to their software architecture, and equally important in how students communicate and coordinate with their teammates. “Writing the reports and communicating with a team feels like overhead sometimes, but if you don’t communicate, you have a team of one,” says Fishberg. “We don’t have these ‘solo inventor’ situations where one person figures everything out anymore — it’s hundreds of people building this huge thing.”
The new faces of flight
Students in the class say they are eager to enter the rapidly evolving field, working with unconventional tools and vehicles that go beyond traditional applications.
“We continue to send rovers to extraterrestrial bodies. But there is an increasing interest in deploying unmanned systems to explore Earth,” says Roy. “There’s lots of places on Earth where we want to send robots to go and explore, places where it’s hazardous for humans to go.” That expanding set of applications is exactly what draws students to the field.
“I was really excited for the idea of a new class, especially one that was focused on autonomy, because that’s where I see my career going,” says senior Norah Miller. “This class has given me a really great experience in what it feels like to develop software from zero to a full flying mission.”
The Design and Testing of Autonomous Vehicles course offers a unique perspective for instructors and TAs who have known many of the students throughout their undergraduate careers. As a capstone, it provides an opportunity to see that growth come full circle. “A couple years ago we’re solving differential equations, and now they’re implementing software they wrote on a quadrotor in the high bay,” says How.
After weeks of learning, building, testing, refinement, and finally, flight, the results reflected the goals of the course. “It was exactly what we wanted to see happen,” says Roy. “We gave them a pretty challenging mission. We gave them hardware that should be capable of completing the mission, but not guaranteed. And the students have put in a tremendous amount of effort and have really risen to the challenge.”
