    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.

Prime fun 1 / 3 - This is the standard X&Y (binary AND) Sierpinski triangle picture but only where X & Y is a prime number. perhaps revealing a relationship between primes and binary AND #math #primes

u/donbright

(note white = X&Y is prime, black = X&Y is composite)

this is really nice. retro and mathsy at the same time!
