The Ulam Prime Spiral
Inspired by the square spiral of Stanislaw Ulam, the prime numbers are plotted on a spiral number line. Each prime on the wound line is marked with a dot. Adjusting the tightness of the winding and the density allows different patterns to emerge.



For the original inspiration, see http://www.orthogonal.com.au/hobby/mm/images/index.htm.
