This example is most like creating a video player, inserting pictures into REU memory. To make this demo, we take a YouTube video, 8 frames per second for a total of 56 frames. The frames is resized to 128×128 pixels, composed in a strip and reproduced, one frame at a time, with the illusion of an animation. The demo can be stored on two floppy disks or in a single 512KB REU image.
