This is cool! How are these generated, exactly? Something is telling me that's J code, but I'm not sure...

Product matrix of reduced residues (rings). Recursive. The patterns you see are the deep structure of the algebraic space of N.

(Used Java but that was an arbitrary choice).

Oh. I'm going to pretend I know what those words mean :P Looks awesome, anyhow, thanks!

Sorry, assumed you would google it.

Basically, let say you have a set of numbers {1, 2, 3, .., n}. And you remove all numbers -- except 1 -- in that set that have a common factor with n. example {1, 2, 3, 4, 5, 6} => {1, 5}. So {1, 5} is the reduced residue set of 6.

And lets call the product of all primess up to a certain prime as a primorial. (This is just like a factorial, except that we only multiply primes in the range. So, 6 is a primorial since it is 2 * 3.

Now just make a multiplication matrix with that r.r.s. and enter the product of the x and y mod the primorial. That matrix is what is generating those images.

Whoa. Mathematics is always amazing when it's made into art!

(Usually I would, just google it, but you took the time to explain it, so thanks, have a badge!)

Looks like a Persian rug to me. Thanks!

Good observation. Most of Persian Architecture and Art are in fact group theoretic pattern systems.

+Thanks. (I'll pick one just for you, then.)

So then the complexity of the emerging pattern increases with n, I assume?

It appears the answer is no.

What seems to be happening is that it simply gets more resolved. Superimposing generations of n, e.g. {1, 2, 6, 30, 210, 2310, ..., ∞#} and applying the same selection criterio manifest self similarity.
