The Sierpinski gasket, typically made with triangles, is one of the simplest fractals. Adding flies (vertices) makes for squares, pentagons, etc. Moving the flies distorts the shapes. Hover over the buttons for an explanation of what they do. I've seen descriptions on the web of Sierpinski triangles, pentagons, and hexagons, but not the other polygons. This project is based on ngmr's project (http://scratch.mit.edu/projects/ngmr/34276) and magicseth's project (http://scratch.mit.edu/projects/magicseth/17651). I added lots of bells and whistles, including the ability to add more flies and to move the flies. I'd love to see someone add rotations as an option.
