Scanimate Central: a history of computer animation

Welcome to Scanimate Central!

Once upon a time (but not so long ago), making animation with computers was pretty farfetched futuristic wizardry. A few brave souls believed it was the future, and helped start what is today a major industry.

This site celebrates the people, places, machines, and projects that came out of that colorful past. I welcome your inquiries; I try to answer them all. Email Dave Sieg with your questions or comments.


Long Overdue Scanimate News

UPDATED JUNE 3, 2022

Hi! I’m Dave Sieg. Back in the 1980s I was chief engineer at Image West in Hollywood, California. Image West had been set up by Computer Image of Denver, the people who designed and built the Scanimate analog animation computers.

They became popular with advertisers and networks because they could make animation in real time. Image West eventually became a busy Hollywood shop—particularly after work connected with the first Star Wars film.
