LED stripes are easy to interface as they already have controllers. DrHugh made a video display using 10 meters of RGB LED stripes. LED stripes are based on WS2801 controllers that allows 24 bit representation of RGB. Whole display is 50cm x 100cm size and holds 320 LEDs aligned in to 18×18 matrix. With such resolution you wont be able to watch movies but pretty effects are guaranteed.

Display is controlled using AT90USBKEY which connects to PC for uploading video data from custom video editing program. It allows exporting sequence of BMP files. Totally it can hold 16384 frames and display up to 20fps for 14 minutes. Display also can be controlled with IR remote. Demo code include Conways Life, Evolve automation presentations and Nicholson – Bailey insect population models with Belusov-Zhabotinsky spirals.
