I think #1 was the best photograph, but I think #6 should win because it makes really clever use of the moon and the light fixture to add a circular theme to the existing straight lines and rectangles theme. IMHO, the rest of the photos just capture pre-existing shape patterns, while #6 uses a creative angle to create a pattern that can't be seen otherwise. But don't get me wrong, the other ones are still really good.

I wanted to submit a photo to this contest, but it was finals week (eww) so free time was in short supply. This week, I'll have much more free time, so hopefully I can submit something.

PS - There are some REALLY good photographers on IA!
