Various Artists


The color .SEQ animation JUGGLER2 is the Atari ST version of Eric Graham's legendary Amiga demo The Juggler. It shows a robot juggling three mirror balls. The Amiga demo was one of the earliest full-color 3D raytraced animations rendered and displayed on a personal computer. When released in 1986 no other stock personal computer could have run anything like it. The frames were encoded in the Amiga's HAM (Hold-And-Modify) display mode which uses a highly unusual technique to express the color of pixles. This allowed to display up to 4'096 colors on screen which is much more than otherwise would be possible.
