Ideal for keeping yourself entertained when you can't be on your phone, this Tetris t-shirt allows you to play the retro game on your own body. After being inspired by a similar Instructables, game enthusiast Marc Kerger decided to make his own Tetris t-shirt and share how he did it in a video he uploaded to YouTube.
You can play Tetris on a tee by printing a game screen on a plain white top. You will also need four AA batteries, 128 LED lights and an Arduino Uno controller. Kerger also included instructions on the back of his own shirt. Buttons on the t-shirt allow you to move the Tetris pieces.
If you are the parent of a young child, they could also play the game and would likely be entertained by the light up, moving blocks.
