Draw a circle on a piece of paper, and a random point inside. If you continually fold points on the edge of the circle on top of the point inside, then the fold marks will combine to form the shape of an ellipse. [code] [more] [inspiration] [bonus]

Draw some random points on a piece of paper and join them up to make a random polygon. Find all the midpoints and connecting them up to give a new shape, and repeat. The resulting shape will get smaller and smaller, and will tend towards an ellipse!  [code] [more] [bigger version]
