This Pixel Kit Will Let You Play Tetris With Jellyfish DNA

Forget playing Tetris on your phone. Now you can play it with jellyfish DNA. Bixels is a DIY game kit that lets you code your own games using synthetic biology, lighting up a digital display with the help of DNA.

Its 8-by-8 pixel grid is programmed to turn on with the help of the same protein that makes jellyfish glow, called green fluorescent protein (GFP). But you can program it to do more than just passively shine. You can use your phone and the associated app to excite Bixels' fluorescent proteins and make them glow at different frequencies, producing red, blue, and green colors. Essentially, you can program it like you would any computer, but instead of electronics powering the system, it's DNA.

Two blue boxes hold Bixel pixel grids.

Researchers use green fluorescent protein all the time in lab experiments as an imaging agent to illuminate biological processes for study. With Bixels, all you need is a little programming to turn the colorful lights (tubes filled with GFP) into custom images or interactive games like Tetris or Snake. You can also use it to develop your own scientific experiments. (For experiment ideas, Bixels' creator, the Irish company Cell-Free Technology, suggests the curricula from BioBuilder.)

A pixel kit is housed in a cardboard box that looks like a Game Boy.

Bixels is designed to be used by people with all levels of scientific knowledge, helping make the world of biotechnology more accessible to the public. Eventually, Cell-Free Technology wants to create a bio-computer even more advanced than Bixels. "Our ultimate goal is to build a personal bio-computer which, unlike current wearable devices, truly interacts with our bodies," co-founder Helene Steiner said in a press release.

You can buy your own Bixel kit on Kickstarter for roughly $118. It's expected to ship in May 2018.

Watch an AI-Powered Robot Take the Fun Out of 'Where's Waldo'

"There's Waldo" is the name of an AI-powered robot that has been trained to swiftly suck all the fun out of the beloved children's books. As Popular Mechanics reports, the robot can pick Waldo's pom-pom beanie and striped shirt out of a crowd in just 4.45 seconds, "which is better than most 5-year-olds," according to the robot's maker.

Built by creative agency Redpepper, the robot is linked to Google's AutoML Vision service, which was fed 107 photos of Waldo from Google Images.

"I thought that wouldn't be enough data to build a strong model, but it gives surprisingly good predictions on Waldos that weren't in the original training set," Matt Reed, creative technologist at Redpepper, tells The Verge.

The robot's mechanical arm is equipped with a Vision Camera Kit, which lets it snap photos of the page and send them to AutoML Vision to be analyzed. Disconcertingly, the otherwise industrial-looking robot has a rubber hand that it uses to point to Waldo when it's at least 95 percent sure that the man on the page is, indeed, Waldo. Alas, once the machines take over, "Where's Waldo?" will just be one more phrase that future generations won't understand.

How to Rig Your Android Phone to Play Old Floppy Disk Games

Owning a smartphone means you have thousands of games at your fingertips, but capturing the nostalgia of playing a game saved on a floppy disk isn't as simple as downloading an app. Reviving floppy disk games for the smartphone era is a bit more complicated, and YouTube vintage video game reviewer LGR shows you just how to do it step by step.

In this video, spotted by Kotaku, LGR takes an old floppy disk, the same kind you used in your computer class at school, and uses it to play a classic video game on a smartphone. This is made possible with an Android phone, a USB connector, an Android USB adaptor, and a portable floppy disk drive that's about as big as the phone itself. (The hardware doesn't work for iPhones, but if you're an Apple user there are plenty of ways to play old PC games online).

Just inserting the disk into the drive when it's connected to your phone isn't enough to start playing: You need to download a special app that mimics Microsoft's old disk operating system, like Magic Dosbox, for example. Once you have that on your phone, you can use it to open whatever game is saved to your floppy disk.

Because old PC games weren't made for touchscreens, the smartphone gameplay can be a little be a little awkward—but if you're willing to hook a floppy disk drive up to your phone, convenience likely isn't your goal. You can watch LGR's full instructions in the video below.
