The Ulam Prime Spiral

​
number of primes
20165
packing density
110
winding tightness
5000
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.
