Funny How Doodles Change Over The Years...

As I came out of a meeting yesterday, I felt the need to share this with all of you. I pondered the evolution of my "doodles". Remembering that in K-12 my doodles were some amusing battle scenes, dragons, airplanes, Star Trek, and the shuttle. Then, in college they were mostly scribbles and random shapes. Now days my doodles look something along the lines of the one from yesterday! This particular one is in reference to ... well actually, can you tell me what I am designing here?

UPDATE: Found an old notebook this weekend while cleaning out a closet. Here is an example of my old doodles.
