(I feel obligated to note that the Behance page has prints available for sale, which I'd absolutely love for you to buy; I decided to knock my cut down to 0% to bring the prices down to something I considered sane, since I really don't care about making money from it. Edit: Btw, the standard cut I'd get from one of these is about $36. If you buy a print and feel inclined to do something more, find a broke programmer and them a Raspberry Pi with the money you save.)
There is a new demo there since last week,

is the latest (includes models with bumpmapping, FPS arms, some other stuff).
