From the project
Pixelboard game lounge table - hardware (laser cut plans, schematics, PCBs)
The Pixelboard is a 80*40cm lounge table board only 24mm thick, integrating a 10x20 color pixel matrix, 8 touch keys, a linux controller with WiFi and ethernet and even a power supply. All disguised under a dark plexiglass, looking like a regular lounge table until touched...
With the current software (see pixelboardd and pixelboard-config in plan44-feed) you can play tetris (alone or 2 players each on one end of the board), watch Conway's game of life, let text messages scroll over the surface and display small 10x20 pixel PNG images (via web interface).
