I was just watching a commercial for that leveler and was thinking "well, the iPoT has the accelerometer, I'm sure a leveling app could be made for it. I kind of laughed at my own idea then got somewhat serious about it. It could definetly work. Just pop it out of your pocket and then place it on top of a painting to see how straight it is. Of course it would have to be ridiculously accurate, but I have all the trust in the world it could be done.
