    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.

-11 bytes: Eliminated the intermediate k, moved some coefficients around, and swapped hypot for square values which is actually more stable for intersection resolution. Now it will never stop jiggling :D

Currently traced pixel is part of the ball and part of the background therefore collision. Awesome trick. My first time seeing this.

Seems to be easier to find good results if j=i%461 is restricted to primes.

u/KilledByAPixel

nice!
u/pavel

Weirdly the numeric error from approximating pi/3 seems to matter a lot.
u/tomxor

Yeah, I think it's because it causes a deviation in the sequence at j=0. Although the output of 0|3*C(r) generally gives the expected low period of +1,+2,+1,-1,-2,-1 as j decrements, it ends on a 3, but only when using lower precision PI/3. full precision PI/3 pushes all of the 2s into 3s, which can be corrected by lowering the coefficient to 2.9, but this also makes j=0 output 2 which then seems to destroy the complexity.
u/pavel

I tried getting rid of the sin/cos by using hex coordinates but I was unable to make a complex picture. Usually just one of the six slices drew-in.
