He is one of the best businessman i know.. He did some realy good+long animations a couple of years ago so every one knows him and loves his work..Unfortunately, the more talented the 3D artist - the less cunning of a businessman/PR guy he is, it appears.
And now he release about 5 Minutes of animation and some Renders every year (My thinking: He make that 5 Minutes of Animation in about 1-2 Month of Work and release it as WIP over the whole year. Every couple of months when community starts to ask.. he release some parts to keep the cow produce milk). Sounds like a good business to me.
