One of the coolest DIY open source kits I have seen.  The team over at Evil Mad Science has put together a kit to build your own portable gaming system.  Solder it up, and using the Arduino environment, and their promised Meggy Library, you will be able to program a very basic video game to run ont he handheld.  The unit is just begging for an accelerometer, too.  I have added this to the top of my xmas list.

Meggy Jr RGB is a handheld platform for developing your own pixel-scale video games.

Featuring a fully addressable 8x8 RGB LED matrix display, big fat comfy button switches, customizable handles, a lo-fi audio transducer, and even 8 extra LEDs for lives, score, ammo, or level, Meggy Jr RGB is a little kit you won't want to miss. Meggy Jr is fast, programmable, open source and hackable. And fun.

Meggy Jr RGB is a little sister to our Peggy and Peggy 2 LED display kits, and was designed with a different focus-- less soldering, more pixels in your palms. The 8x8 RGB matrix display provides a whole lot of pixels (192 LED elements), and the 8 auxiliary LEDs bring the grand total up to 200. The six tough buttons have excellent click-feel, and multiple programming interfaces let you take control of exactly what you're playing with.

The basic kit will run only $75 (including the case)  Get one here.
