Factorizations

The factors of every number from 1 to 500. Numbers are plotted horizontally, and factors are plotted vertically. A black dot represents a factor. Note that, in this display, any prime number would have only two dots: one along the top row of pixels (since all numbers can be divided evenly by 1) and one along the diagonal (since all numbers can be divided evenly by themselves). The periodic arrangement of the pixels would seem to suggest a (possible) means of finding a function P(n) that gives you the n-th prime.
