Factors: The numbers from 1 to 500 are plotted horizontally across the top row. Along each vertical column, if N divides the number X (represented here by distance across the top row) evenly (that is, if N is a factor of X), then the pixel N pixels down from the top is black.
Prime Factors: The same general principle as above, but in this image, only the prime factors are shown.
Blue Over Yellow: Basically, a combination of the previous two images. Numbers from 1 to 250 are plotted horizontally, and factors are plotted vertically. If a factor is prime, the little square representing it is blue, otherwise, it’s yellow.
That tantalizing structure is still just slightly out of reach…Oh well, back to work!

Nice, will look at more of your stuff when my headache has gone.
