For a while, I had the vision of a recursive painting app. The idea is to let the brush stroke is used as the foundation for the stroke itself. So I let the user make a brush stroke, and then replaces each brush stamp with the entire stroke. Pretty simple.
This is aimed for Android tablets, and I had some trouble getting the framerate down and getting it to accept various aspect ratios. But now it runs smoothly. I think it's a fun little toy! But it does need lotsa work! Constructive suggestions and harsh criticism are welcome!
