That is awesome. The level of smoothness and straightness to the edges of the fondant is unbelievable. He could've made the support bit in the middle look like R2's third leg, though...

@ADMNAISMITH - I don't know about the cake in the post, obviously, but it can certainly be done without styrofoam (the support dowels are largely necessary in tall cakes). Here is one I made myself, for my girlfriend's birthday last year; it's life-sized and started as a stack of six chocolate cakes... Linky to Cake. Pardon the crappy cellphone picture quality.
