The first demo is a replica of the original Amiga Boing Ball demo. All graphics were taken from the original demo and adapted for the Lynx, same with the sound sample. It uses multiple frames of animation for the rotation of the ball. The audio pans left and right with the ball on the Lynx II. The shadow transparency is created by drawing the shadow sprite every other frame. This will only look right on the original Lynx display, because of the slowness of the display.
