Thing 22: Retrievr--an intriguing Flickr mashup

I found Retrievr to be fun. With an easy to use (though hard to use effectively) tool, you draw an image in a little box, and then an assortment of images than are alleged to match what you drew pop up along side of it. If you could draw more precisely and if the photos were more closely matched, this would be very useful. As it is, it's more along the lines of messing with mandelbrot sets.
