If you like geek decor, then Gadgets and Gear has just the thing for you. These are Metal Core Door Wall Graphic Decals and they come in 4 different styles: airlock, armory, freight elevator, and lab door.
Personally, I think putting the Lab Door one on the guest bathroom door would be awesome.

You can pre-order them now for $60 or buy then for $80 when they come in.
