2    It uses at least one while statement in a nontrivial way. 
3    It uses at least one if statement in a nontrivial way. 
4    It features both circles and squares, all created from just one circle and just one square. No rectangles. 
5    It creates the exact same image every time it is run. 
6    There is some chance that the casual observer might find the image interesting!
