Triangles and Circles

When Katie and I were vacationing in North Carolina and Philadelphia we, as usual, took a lot of pictures.  At some point I guess we were lounging on the beach being bums and decided to make our logo out of... stuff.  Pretty much everything on the beach became triangles and circles and here they are for your viewing pleasure.

I think the one with our hands (mine is the one with the blue nail polish, Katie's is the pink) or the one with the sunglasses is my favorite.  What's yours?
