    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.

Variant where the distance scale factor is 1/2 plus-or-minus a little bit. Also some code golfing

u/taupelink

I think some of the pattern details are an artifact of the way I golfed the code...of whatever the values of sin(i*540 radians) are, for integers i=0,...,539

Riff off of Katkip's great dweet two days ago. This is what happens if you floor the rotation angle.

Nice! If you edit another dweet you can hit Remix to post it.

An alternative #shuffle. Takes a little longer to find those last values. H/t to u/joeytwiddle for a golf tip using binary arithmetic

bored math test with random

u/Fime

Golfing tip: When calling a random function often you might want to use r={valueOf:Math.random} instead. You then get a new random value when accessing r like a normal variable (no () needed)
u/f8f82804

If you're willing to re-use an already-declared variable you can save a couple more characters: T.valueOf=Math.random
