My Earliest Abstract Work of Art

I recently came across this abstract art project from my elementary school days. It was created by lining a shirt box with a piece of paper, tossing in a marble or small rubber ball, and some blobs of paint. The magic is made by closing the lid on the box, and with a few random shakes of the box, the ball rolls around through the paint. When you remove the lid, there is a surprise work of contemporary art on paper. I always loved this painting. It's my very own Jackson Pollock- style work of modern art.
