I'm headed out of town for a day or two and don't have time to get a good shot before I leave so here's an abstract of a bad shot :)
Hmmm strange. I looked again and this has some optical illusion characteristics. Look closely and in places one piece seems to overlap another and then it changes so the part that was in back is now in front. Very 3-D
Oh yeah, I meant to do this. I'm just good that way.
