Spark Fun Electronics has made a name for themselves recently by selling interesting parts like this $20 color LCD. Hack-A-Day reader [Refik Hadzialic] decided to buy one and see how easy it was to use. It is a 128×128 display and should be a clone of the one you would fine in a Nokia 6100. He wired it up to an ATMega32L-PI8 microcontroller. He grabbed source code from a couple different places and eventually got something to work. In the end, the actual control commands seem pretty simple. Refik has been posting a lot of quick projects and info on his site, e-dsp. Have a look.
