    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.

Hi there :) I had to delete #1215 because it froze the browser (due to some excessively deep recursion or something). Here's the code, for reference: (F=Z=>{for(x.fillStyle=R(W=2/Z*1e3,W/2,W/1),i=Z*Z*2;n=i%Z,m=i/Z|0,i--;n%2^m%2&&x.fillRect((n-t%2-1)*W,(S(t)+m-1)*W,W,W));Z&&F(Z-5)})(36)//rm

Do you have to use Math.pow here? Can't you use ** instead?
