Ever wished you lived in a restricted underground lab where all entryways are locked by steel doors plastered with warning signs like those found in sci-fi films?  Well, you can finally turn your dwelling in mum's basement into one of those with the Sci-Fi Door Decals.

A set of removable decals sized to wear on doors, the decorative panels can turn the entrance into your erstwhile boring bedroom, dorm room, and bathroom into a door straight out of a sci-fi movie set.  It's designed strictly for smooth and semi-smooth doors, so it probably won't work with your front door, but most other doors in the house should be fair game.  Plus, you can plaster it up a wall with no actual door to trick guests who ask where the bathroom is -- should be good for a couple of laughs.
