Pretty cool app with steampunk style graphics; Acme Lie Detector. It's a prank detector that lets you pick the answer. Tilt the phone in the direction of the result you want and mess with people. First you ask questions you know the answers to like "what day of the week is it ?" or "who is president?" so you can prove the accuracy then ask them if they drank your beer or want to sleep with your gf or whatever...

I made a screen grab and use it as my wallpaper for the steampunk look
