"Dean," a Carnegie Mellon freshman who is tired of his dorm-mates getting locked out of their rooms has developed a door-unlocking tool that consists of a length of copper wire that "slides under the door, flips up and grabs hold of the handle on the inside so that you can pull it down" -- inspired by a classic MIT pranker's tool. He details it here.

You can keep it in your pocket!
I also bought some 1/4" wide 20 threads per inch bolts (which fit right into a standard camera tripod hole) while I was at Home Depot. I figured the tool would be more useful, and look less suspicious as a tripod.
