I’ve been playing Bejeweled on my phone lately, and while on the way to work this morning I had an idea: one of these 8×8 RGB LED matrix displays would be a great interface for a touch-sensitive standalone version of the game. You could use the LEDs themselves as touch sensors, multiplexing them as both inputs and outputs. Pack it up in a sleek little aluminum shell and you’ve got a fun little party toy.
I’m not going to build this.
