    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.

oooooh, I love dithering! Nice one!
u/tomxor

me too :) I didn't realise how simple the algorithm was before no, and it can be done in a single pass because it's only half a 2d kernel. Tweaking the coefficients (*R) can be fun, e.g 7*R=>5*R, 3*R=>5*R better preserves the dark and light areas in this image.

Here is 12 characters saved: c.width^=i=0;for(y of'111121012110')x.lineTo(960+y%2*S(p=t+1.6*'123403020140'[i++])*(z=1600/(3+y%2*C(p))),y*z);x.fill('evenodd')
u/f8f82804

using 1.6 to approximate Math.PI/2 is OK, but you should change all the 4s to 0s in the second data string, just to minimze the aggregate angular error. I used 4 for clarity, because 1.57 is accurate enough that the error is hard to notice. With 1.6 you can notice that one edge is longer than the others. c.width^=i=0;for(y of'111121012110')x.lineTo(960+y%2*S(p=t+1.6*'123003020100'[i++])*(z=1600/(3+y%2*C(p))),y*z);x.fill('evenodd')
