Spotty sent me a special version of the foo race video (I know that because he says "haha odin" in it), and I must say that it's full of crock. Spotty has used a total of 5 tilesets (Tubelectric, Castle, Diamondus, Da*n, and Carrotus), while 1.25 is purported to support up to 3.

Edit: Oh yes, and a hocus tileset, as well.
