I helped work on all the pre visualization When Terminal Reality.  I built the
first prototype proton pack.  It was later remodeled and modified to fit the
game play better.
This was built right before ZBrush hit the scene and normal maps became
the norm in games
The first Stay Puft was very round and cartoon like. I built a second Stay Puft closer to what was in
the first movie. I built it with proper topology for animation.  Though he got re-textured and normal
mapped my model made it into the final game.

I also did a lot of Pre-Viz animation to help get the feel of how he would walk and move around a big
city.
I also did all the Pre-Viz for Slimer.  I did a lot of R&D on getting him to have squash and
stretch.  Back in 2005-2006 game engines didn't support scale on joints.  Terminal
Reality got scale working allowing the animators to add another level of detail improving
the quality of there work.
