Primes have always fascinated me despite not being a mathematician. Counting numbers are regular yet the pattern of primes seems not to be (although there is a way of plotting them that makes pretty spiral like structures).

I think just about every non-mathematician has at some point been enamoured with either primes, or pi.

Same here.. My fascination began when I learned about Glitch Primes, Cyclops numbers and the bloody Riemann Hypothesis!
