Forum:My megaton/tenpenny home themes?

I heard you can change the themes of your homes (either megaton or tenpenny, depending on your choice in "power of the atom"). My question is...how? There apears to be no information as to how to do this on this sight, simply that it can be done. And dont tell me to talk to Moriorta or the guy from tenpenny who sells you the suite improvements either...tried that already. Any information would be most apreciated. thanx
