COOL Graphic Display
Worked fine for me but remember to hook it up correctly and when using with our Arduino you have to make sure you have the correct libraries installed, which are not by default.

Worked great until...
Worked great until it didnt. I used this for a display on an Arduino based AC power monitor- ran about 30 hours continuously, then died. I will probably try another as I dont want to redo all of the code- just hope the next one is more reliable.
