The Color LCD Shield interfaces your Arduino with a knock-off 132x132 Nokia 6100 LCD. The LCD is available with one of two controlling drivers - a Philips PCF8833 or an Epson S1D15G10.
A really great resource for working with both the Epson and Philips controllers is Jim Lynch's Display Driver tutorial. Much of this example code stems from that document.
