Its beautiful. It has an interesting formation of an infinite coaxial cones. with semi vertical angles arctan(1/3), arctan(1/5), ... arctan(1/(2n-1))... (The even numbers slopes form the progression of circles on the top). Although that doesn't give the pattern of the primes, it is formed because every number has a multiple for each natural number.
