f you feel the gadget world has become too boring and predictable, Google's Japanese division is here to restore your faith in technological absurdity. Company engineers have introduced the Gboard Kuru-Kuru project—a vertical keyboard where keys are mounted on an endless belt of a rotating cylinder. Instead of tapping away at flat buttons as usual, you are invited to spin this barrel in search of the right letter, breaking decades of ingrained muscle memory.
Google's Japanese branch published the 3D printing blueprints and firmware as open source, allowing enthusiasts worldwide to build this marvel of engineering themselves. The company calls it an experiment, but in reality, it is a pure cultural phenomenon of Japanese April Fools' jokes unexpectedly taking physical form. Why waste resources on something that makes typing even a single sentence without a nervous breakdown entirely impossible is a rhetorical question, but the blueprints are already online for anyone who wants them.
The anatomy of the endless barrel
The device's main feature lies in its form factor, which replaces a flat layout with a cylindrical conveyor belt. To find the desired character, you have to spin the structure by hand, turning typing into an attraction from the past century.
Engineering feature of the Gboard Kuru-Kuru: an endless belt of keys on a rotating cylinder, requiring a completely new approach to typing.
Instead of speeding up your work, this design slows typing down to a turtle's pace, forcing you to literally twist your fingers just to type a comma. It is a classic example of technology born clearly not for market success or consumer convenience.
DIY culture versus common sense
What is funniest about this story is the open-source nature of the project, turning a tech giant's joke into a kit for home workshops.
Open DIY nature of the project: Google's Japanese division published 3D printing schemas and firmware, letting anyone build the device themselves.
If you have access to a 3D printer and plenty of free time, you can spend your evenings assembling the case, soldering the board, and setting up the rotating shaft. Just keep in mind that what you get in the end is not a utilitarian work tool, but a shelf souvenir showcasing the depth of corporate engineering self-irony.
Who needs this and should you buy it
From the perspective of a regular buyer looking for everyday working tools, the Gboard Kuru-Kuru makes zero practical sense. This is neither a typing tool nor a cure for wrist fatigue, but a purebred exhibit for tech geeks with too much time on their hands. Spending money and hours of your life assembling this cylinder makes sense in exactly one scenario: if you genuinely want to support the absurd spirit of experimentation in an industry where everyone else long ago moved to boring, thin slabs.
Key takeaways
- Google Japan released open blueprints for the Gboard Kuru-Kuru, a vertical cylinder keyboard designed for 3D printers and DIY assembly
- The device replaces a standard flat layout with a rotating barrel, deliberately making typing slow and wildly inconvenient
- This is a pure experimental project and a physical April Fools' joke, carrying no practical use for real work
- You should only build or buy it for the sheer fun and novelty if you have a 3D printer and extra time
