Movement and Asymmetrical Balance

For the design principle of Movement, I used my faithful toy tractors again. This time they were moving billiard balls around. The loader tractor on the left is pushing the green number 6 ball, which in turn has moved the other three balls. The little backhoe loader on the right is ready to corral the moving yellow ball.

This picture also demonstrates the design principle of Asymmetrical Balance. The top and bottom background is divided unevenly. The tractors are on the right and left thirds of the photo, while the billiard balls are located in the center to bottom third of the picture. The balls are coming out to the viewer, as the viewer sees the balls and looks further into the picture to see what is behind the moving balls.
