Over at dannychoo.com, they ran an otaku bedroom contest. Whoever had the nicest bedroom won. Some of the entries are very impressive. Here are some of the ones I liked.

I actually do admire these guys for their devotion of manga/anime and their massive collections. I don't collect anything so my room is pretty plain. However I could never date any of these guys cause there no way I could ever have sex in a room like that!
