This Sierpinski's carpet is made from only the chaos game by drawing 8 points at the tips of the triangle and having a dot randomly picking a point and drawing a dot at 2/3 between 1 out of 8 random points on the screen. Then it uses the newly drawn point to do the same over and over causing the Sierpinski triangle to magically form.
