Mechanical Fish and Cardboard

I was thinking about fish, and machines. 

I cut up some cardboard, tore one of the edges, and scanned it. I made a drawing of a fish with a Sharpie on paper. I scanned my drawing. I put them all together, added some color, and text. Now I have a picture of a mechanical fish.

Feel free to think about fish, machines, and cardboard. Something good may come from it.
