Fractals are geometric shapes that "nest" so that each shape is a rought copy of the whole. Plus they're fun to watch. This isn't my formula, I just adapted a justBasic sample project and added a pause feature (click the stage). Space to get a new shape, and the slider controls the X/Y height (or zoom) of the next pattern. I'm working on a way to zoom in on the current shape, but then again, I'm "working" on a lot of things ;)
