This is beautiful! Not just is it really quite cool to explore with, but is truly gorgeous. It is true as another user put that this is a graphical way of looking at a sieve of Eratosthenes, but to say that it is is “only” suggests to me a lack of appreciation for the beauty (plus, it also maps other non-prime patterns: deficient, perfect and abundant).
