Here is a hack to extract, and use the LCD from a cheap picture-frame key chain. The project involved desoldering the LCD from its mainboard and building a breakout for it. With the help of a DSO it was possible to find out the pin-out for the LCD.
The AVR library used to drive this LCD is available for download at the bottom of the source article. You can check out a video of this project below.
