To celebrate the 30th anniversary of Tetris, Marc Kerger created this Tetris t-shirt. And yes, you can play the game on it! It looks hard though.
It uses an LED hack, with 128 LEDs, an Arduino Uno microcontroller board, 3D-printed housing and soft material for the buttons and two Adafruit Matrix controllers. The t-shirt needs four rechargeable AA batteries to power the game.
