A painting with lots of different colors on it.
A piece of artwork is displayed on a black background. The artwork is very abstract and has a lot of different colors. There are a bunch of large wheels that are drawn in a way that looks like a car. There is a green circle in the middle of the artwork. There appears to be a lot if a train or a train engine.
