arduboy 

An arduino Leonardo based device with a 128 X 64 screen. An arduboy is in the form factor of a credit card, and can fit in most wallets and credit card holders. The main method of transferring games is flashing then via a computer. It is only capable of having one game at a time before being reflashed through some other device.

My new arduboy is so cool!
