The winner is Zachariah Scott with the "Survival of the Fittest".
Description from the author:
Survival of the fittest is a quick little short which was a finalist in valves saxxy awards this year. It was a quick project designed to get a feel for the software, and I am extremely pleased with he results ipisoft allowed me to achieve. All body animation was created using the ipisoft program, with minimal hand keyed cleanup for the character fingers and faces. The thing that impresses me most about ipisoft though , is the massive boon to production speed it provides. I was able to build the entire short in a mere two days, with only 6-8 hours spent dealing with animation capture and processing. This software is blisteringly fast and efficient when placed in the right hands. I'm seeing serious improvements in my animation pipeline, with massive gains in speed and fidelity thanks to this wonderful software.
