My Son and Symmetrical Pirates

I just want to highlight an interesting thing Toby did during one of his quiet times. He played in his room for about an hour and then came out to tell me that his pirates were having a battle. He asked me to take a picture of their battle. Check out the mummies (which he calls "mommies") on the left. He arranged all these toys all by himself, and I've got to say that I'm pretty proud of the symmetry I see there. (That's the former math teacher in me!)
