I was watching a show where someone had a wall safe hidden behind a piece of artwork. And I wondered, how cool would it be to be able to install a piece of artwork over a safe, locker, or cabinet? The furniture would take on the name, appearance, description, weight and value of the artwork. But with the right amount of perception or intelligence versus the quality of the artwork itself, you could examine it to get the regular commands for the furniture. Something like that. Uninstalling the painting would reveal the furniture as normal.
