Well I think you accomplished your goal. I definately lingered longer on your shot than I would have if it weren't for the title. My score didn't change one way or the other but, I did look longer. I gave you a 5. It didn't jump out at me as one of the great ones but I didn't see anything wrong with it either.
OK, there was no dog shape. But, the image reminded me of those picture games that force you to look for different shapes. My goal was to have to linger over the picture and just play with the shapes for awhile. It may have helped and hurt my overall score, but I am just glad you all had fun looking at it. (One person really hated it and scored it as a '1') I guess you cannot please everyone, but I did have fun. Thank you for the comments.
