This photo was taken last week on my trip to Washington, DC. I think it's interesting because the positive and negative spaces play off each other in a very odd way. The longer you look at it, I think the more this becomes apparent. It's a very graphic/pattern shot, and the light and dark shapes begin to fool the mind as to whether the blocks are raised or recessed. Please comment if you'd like to guess what it is. I'll be posting more from this same location this week that will put it in perspective.
