WTF...
Whilst this is incredibly well done I swear it freaked the living s**t out me when I first watched it.
The videos below are made by a guy called GregMutt who used Lightwave and Softimage to animate a purple dog-like creature for a genuinely funny mini review of Avatar, and then a follow up vid talking about his Youtube popularity.
Seriously, you have to watch these. Awesome skills.
