Cool site www.tineye.com

I ran across an interesting site today. TinEye searches images to see where they come from initially or to find similar images -- so, if I take a photo from, say, the Globe on line, and post on my blog, TinEye will identify it. Or, more surreptitiously, if I post a photo taken from some other site and claim "it's me" TinEye will identify the fake. Take a look... .
