Here is some work I did a while back for a company called Supermassive games. I was creating concept art for a new game called Tumble that has just come out with the Sony Motion Controller. I worked on the early development for the game so it looks a bit different now. I've got some more stuff somewhere that I'll try and dig out. The idea for the game was to stack blocks in various ways, with the blocks providing some kind of interaction as you played with them.
