    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Further optimized the is_prime (F) function. How far can you scroll before timeout? :D #prime

u/fujimotos

It's kinda surprising that the distribution of prime numbers has such a noticeable pattern.
u/firegodjr

Well, primes are still technically pseudorandom. They don't form a noticeable pattern, per se. This algorithm would possibly work with any consistent pseudorandom number generator, but this pattern is uniquely made up of prime number interactions.
u/lionleaf

Well, non-prime numbers definitely have a pattern that I would expect helps making this very beatiful. For instance ever other number is not prime (even), every 5 number, every 7 number etc. So lot's of regularities.
u/fujimotos

Yeah. I see Math.random() > 0.5 produces a pettern looking nothing but garbled noise. In comparison, the one generated by prime numbers is a Persian carpet.
