"Prime Remainders" visualization

I was pointed out to the J-Blog's post: Prime Remainders. From the blog:

This program calculates primes, takes their remainder and then places a color accordingly. The formular for the color c at prime p with modulo m is c = p mod m.

It is a one-liner in Wolfram Language:

ArrayPlot[Partition[Mod[Prime[Range[350^2]], 450], 350]]

enter image description here

Reproducing the original color scheme is simple:

ArrayPlot[Partition[Mod[Prime[Range[350^2]], 450], 350], ColorFunction -> (Blend[{Black, Red}, #] &)]

enter image description here

And the app:

Manipulate[ArrayPlot[Partition[Mod[prm, mod], 100], ColorFunction -> (Blend[{Black, Red}, #] &)],
 {{prm, Prime[Range[10^4]]}, None}, {{mod, 250}, 3, 1000, 1}]

enter image description here

I would recommend checking out New Kind of Science book especially Chapter 4: Systems Based on Numbers for many interesting patterns generated by numbers.
