I think that they are all very cool, but the one I would love to have is the Star Trek one:
I know I'm known more as a Star Wars geek, but this room would make me feel like I was actually on the bridge of the Enterprise. I like to imagine Picard, Data, Worf, and the rest coming up there for movie night.
Picard: Mr. Data, what is the status?
Data: Sir, the "popped" corn has been fully hatched, awaiting the addition of butter and salt.
Picard: Make it so.
Worf: Sir, we have the movie "Bridget Jones' Diary loaded in our memory banks.
Anyway, check out the link and let me know which one you would like. Or is there a theme not listed that they should make?
