From the Youtube page:
Created totally with NewTek's LightWave 3D modelling and rendering software and NewTek Video Toasters on Amiga computers, in the early 1990's.
This video was ripped to MPEG from a very high quality promotional VHS tape. This video was a monumental achievement in 3D animation for its time in the early 1990s and it was done COMPLETELY on affordable, personal computers.
Todd actually used a stack of ten Amigas
(because it would have taken forever to render this many frames of 3D animation on a single machine).. and was sneakernetting SCSI hard drives
between them since Commodore, Amiga's maker, would not provide him with networking hardware
to make the rendering of the thousands of frames in this video easier. He did most of the 3D object modelling and animation scene plotting himself.
So he's not just a singer / songwriter, but a VERY talented artist and computer wizard too. He originally intended the video to be 100% 3D rendering but Warner Bros. insisted that he appear in it, so he filmed himself in front of a black backdrop and then overlayed the film of him singing the song onto various 3D objects in the final rendering, ... much more on YT Video page, ...
