Is there a color LCD display for an arduino? I currently have a Mega2560 with the LCD4884 Shield. The Shield is good for putting out text and simple pixel images. But I am wondering if there is something that has a full range of colours that would work with the Arduino? The screen size would only have to be a few inches in size.
There are actually several shields that have color screens on them. Many of the shields are just regular mini TFT displays, however there are also touch screen ones.

Here is one from Adafruit that includes a MicroSD holder and a Joystick.

Here is one from Radio Shack that features a 2.8 inch screen with touch capabilities 

As far as screen size, many of the screens are only about an 1 inch across, however the biggest I have ever been able to find are 2.8 in.
