I can think of at least a half dozen contests using this image, but I'm all out of money for contests right now. Just for funsies: There's a recursive image in this composite mosaic. Describe the image -- i.e. what is on the image -- and point out the approximate location of at least one instance of this recursive image. I might create another mosaic in a couple of weeks and have a contest then. In the meantime, please feel free to shoot some ideas to me on a bikey mosaic you would like to see.
