The Time Machine.

Constructed from a small circuit board from an old video and a couple of old clockwork watches, this small model is a tribute to the famous and fantastic eponymous device designed by Wah Ming Chang for George Pal's famous 1960 film version of The Time Machine.

Aside from building this fabulous mechanism for which his company would win an Academy Award, Wah Chang became well-known for his model and props work on Star Trek and The Outer Limits having started his career at Walt Disney Studios working on Bambi and Pinocchio.

He died in 2003.
