Cross your eyes til the red/green marks overlap, then look up and down the pattern adjusting your depth of vision as if you're looking from your feet towards a horizon.

It's a pattern that forms when you plot the divisors of numbers arranged along the x plane so they extend down along the y plane, nothing else is done besides blanking out the primes.
This particular section is near the fifth perfect number (
33550336, a number which is the sum of it's divisors, 1 + 2 + 3 = 6), and especially striking.
