In the Factors Demo, could you change the degree when you paint the next star? Maybe even change the degree between the factors the same as the first one. I think that might look a little nicer.

I think I know what you mean. The factors are drawn as a tree, and the way things are drawn now, it's possible for the line segment drawn for a child to go partway along the line segment drawn for its parent. Do you mean that I should rotate the children slightly so that this sort of alignment doesn't happen?
