Pumpktris allows trick-or-treaters to play the retro game on a hacked squash.

For Halloween, tech-enthusiast Nathan Pryor wanted more than just a Jack-o'-lantern. Pryor replaced the candle with LED lights and instead of a scary face, he carved 128 tiny squares instead. The end result is the “Pumpktris,” a squash with a playable Tetris game.

Pryor wrote a detailed post on his blog of step-by-step instructions on how to create the Pumpktris. In a nutshell, it involves a lot of planning, soldering, coding, and of course, pumpkin carving. See the playable pumpkin in action below:
