Lady Ada intros her latest project, the “Pong” Clock. It’s cool because time only changes when a player loses.
I would also like this to be implemented with a Tetris game, that would be a lot of fun to watch and kill time. Or even better, your dog or cat might enjoy watching it for hours non-stop.
Based on Atmega328 microcontroller, the Pong clock can be hacked to your liking using the open-source code provided here.
