If you thought phones were boring, Google Japan has a surprise for you! After the cool transparent phone wallpaper, the Japanese branch has come up with another crazy idea: a physical keyboard that moves like a conveyor belt!
This is one of those devices you can immediately tell comes from Japan. The crazy concept was unveiled on October 1st on Google Japan's official blog. The date is not random. October 1st has become the day for crazy keyboard concepts, as 10/1 is a nod to the 101-key keyboard.
This time around, Google Japan has decided that moving your fingers is too much of a hassle and the keys need to come to you.
The Gboard Kuru Kuru is a keyboard that looks like a treadmill. The Kuru Kuru name comes from the Japanese sound word that imitates a spinning motion.

Instead of using your digits to find the letter or number you want to type, you just place your index finger in front of this strange contraption and wait for the right key to come to you.
It's a very inefficient way to type, but it's something that will absolutely kill at parties. Google describes it as a "Copernican revolution" in text input, making a reference to the heliocentric model of the solar system.
You can't buy this thing, but you can build your own

Sadly, Google isn't planning to build this crazy concept en masse and sell it to you. It's part of an annual tradition of creating wacky keyboard concepts.
You will need a 3D printer for the plastic parts and several trips to the hardware store for additional components, but the project is absolutely doable.
You can, in fact, build two of these and use them with both hands for the ultimate and most bizarre two-handed conveyor belt typing experience.

Digging through the Japanese page of the project, I found various keyboard concepts from the past. One uses phone-like rotary dials to jolt you with instant landline nostalgia.
Another cool concept from 2024 reimagined the keyboard in a Möbius strip donut shape. Frankly, it looks like an alien artifact.
