Katamari Damacy cake
I'm about to reveal my inner geek with this post, but I am so working on this cake on my next day off.

Katamari Damacy is a funny little video game where you use this giant ball to roll things up, then the ball is thrown into the cosmos to become a star. Strangely addicting, not to mention it just makes me happy. And I'm not the only one.
From an article on mtv.com about the Katamari craze and another person who has baked a Katamari cake:
"Kris Garland, an artist in Seattle, decided to bake a Katamari cake. "I was thinking in terms of structure rather than taste," she said, noting that the spherical shape of a Katamari posed a baking challenge. Garland decided to bake two hemispheres, merge them, ice the spongy sphere and apply cupcake tops for the Katamari's signature bumps. She wound up with a five-pound cake and posted the photos online (at Flickr.com)."
As the King of All Cosmos might say, "We are moved to tears by the size of this thing."
