This was really interesting. Creating movement with only a white sheet of paper and a couple of black squares. I never thought about this. When I am creating something, I always want to position the focal point in the middle of the surface I am working on. Simply because I think it looks cleaner. But I actually like the samples where the black squares are not in the middle or in a orderly line. I think it becomes visually more interesting to place the black squares in a seemingly random fashion.
