What is going on in that head?

When I asked my little-man-of-few-words what this was, he answered, "door." Now, "door" has multiple meanings (house, barn, shed, car door, door, or sometimes something completely random, like cat)and should not be confused with "da da door" which of course means "duck house." Obie likes to build pretty much anything with any materials that are at his disposal. We like to think that these creations are a "window into his brain." (How do you like that psycho-babble?) Anyway, we especially liked this creation and how it suspends itself out from the coffee table. Pretty cool!
