Marc Kerger has posted a video on Youtube (via Polygon) of his delightful playable Tetris t-shirt - created to celebrate the 30th anniversary of the Alexey Pajitnov's classic puzzle game.
"Here is a project I just finished, just in time for the 30th anniversary of Tetris. a T-Shirt you can play. with an arduino uno, 4 AA batteries and 128 LEDs. I always wanted a playable Tshirt, well now I made one myself," writes Kerger in the video description.
We can only assume Kerger enjoys being touched on his stomach as this shirt will likely attract a lot of attention.
