Curtains.

[Tomzeh]

I know, this idea has probably been mentioned thousands of times.
Anyway, i was thinking curtains that work like hatches, only people with rites can open/close them.
Double click them and they open/close. They can go anywhere in room, if not behind a window behind the curtains is the cloud scene, so you can add multiple windows!

I was thinking more along the lines of put-on-the-wall posters. :)

Your original post says that they would go anywhere in a room :)
