    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.

Oh woops it should be c.height|=p=m=>(S(Y+t+m*90)+1)*250;for(i=108;i--,Y=(0|i/4)*40;a<b&&x.fillRect(a,Y,b-a,40))x.fillStyle=R(a=p(m=i%4),50,b=p(m+1%4))
u/Purpzie

Okay dwitter hates me now, there should be a newline afterc.height|=
u/Purpzie

Honestly there should be an edit button for comments. Forgot to mention I changed the color but it has no effect on code length
