I think the far more interesting part of the Skrumps is that it renders in real time. When the puppeteer is performing the character is when you see the character. On the "Jim Henson Hour" episode "Secrets of the Muppets", he showed a computer generated character they were using (was it called Waldo? don't remember) and when he performed the character live, it was very rough animation because the computers at that time weren't able to render it fast enough, in real time. Now the computers are a million times faster* and can instantly render the character as it is performed. So it is now possible to have a live animated television show! The puppeteers are the animators and they can perform the characters instantly. Wrap your head around that. *"a million times faster" is a rough estimate. Your mileage may vary.
