Dinosaurs were always good for a mouse-drawn exercise since this was before scanners and tablets were easily available.
Spaceships and dinosaurs always make good subjects for practicing animation. This 1989 animation combines 2D and 3D animation as well as spaceships and dinosaurs and was just fun to do.
This trade show animation was based on their brochure illustration which showed an ohm meter as a railroad roundhouse with computers and 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 "Tron-like cycle" electrons zipping along the edges of the tiles.
More dinosaurs, this time evolving.
