My first Arduino project, a DIY Arduino UNO video console with a game which is neither space invaders nor asteroids!
The whole game is in single file, requires 2KB of RAM, and ~18.5KB of flash. Some things still need to be done, in particular more/better levels. More details in the source code.
Special thanks to Myles Metzer for his impressive TVout library (http://playground.arduino.cc/Main/TVout) and to Panicz Godek for introducing me to ANSI C bitfields.
just plug 4 switches (with 10K resistors) to pins 3,4,5 and 6, plug tvout (http://playground.arduino.cc/Main/TVout), and it should run.

If it fries your TVset, your arduino, or both, that's neither my responsibility, nor my business.
