ESP8266 Arduboys
Have you seen the ArduBoy? This thing is really cool! A thin tiny game system. Based on Arduino and programmed via the Arduino IDE. There are quite a few games developed for it. And a lot of them are really great fun. The software running these is open source and easily modified. Given that I want to build my own stuff I decided to take a stab at getting the system to run on the arduino compatible esp8266.
