Fun idea, but what are the potential use cases? The results seem quite random, even the same image drawn slightly differently returns wildly different results.

Fun idea, but what are the potential use cases? The results seem quite random, even the same image drawn slightly differently returns wildly different results. Tried finding logos with it (http://bit.ly/mOHZjx http://bit.ly/mOHZjx, http://bit.ly/rpHUOC http://bit.ly/rpHUOC), smiley face (http://bit.ly/p9EqV6 http://bit.ly/p9EqV6), Piet Mondrian (http://bit.ly/pSxzap http://bit.ly/pSxzap) and schoolboy's favorites (http://bit.ly/pYMeV6 http://bit.ly/pYMeV6 http://bit.ly/nr7wxf http://bit.ly/nr7wxf) with no joy. Anyone got it to find anything they specifically asked for? Edit: Last two NSFW if you work in a preschool or something.
