Electropong aka Pongmaster
I have built my fair share of beer related devices. Here is one that really impresses me. Powered by a PIC18F6622, it has all the makings of a fun project (Blinky LEDs, a scrolling matrix, etc) the most impressive part is that he even tried to simulate the feeling of the cups when they are filled. The only thing that disappoints me is that there is no requirement for drinking while playing the game which seems to defeat the purpose. Check out his whole write up here.
