In Fallout NV I'm using a very nice house mod, called underground hideout. The cool thing about this house is, that when you progress through the game, your house gets nice additions, like statues or posters about quests/locations you've done. There are also scripted weapon walls which allow you to automatically arrange weapons and it helps to check if you've collected all unique weapons.

Does anyone know of a similar mod for Skyrim, where your house actually changes (in a subtle manner) as you progress the game? Would be nice to help track completion of the game.
