This animation from 1990 was for a computer repair company that needed an animation loop for tradeshows. It was based on an illustration on the cover of their brochure which showed an ohm meter as a railroad roundhouse with computers and computer parts traveling in and out on tracks. To animate that was beyond the capabilities of the ST so I traded off by having a capacitor with the company initials fly through the roundhouse where the company benefits could be listed. It may be hard to see at this size but if you look closely at the tiled floor you'll see where I put in "Tron cycle-like" electrons zipping along the edges of the tiles.
