    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.

Shortened by 18 characters: for(x.globalAlpha=.3,j=900;j--;)x.fillStyle=hsl(${j-t} 99%50%),x.fillRect(960+j*S(t+j),540+j*(S(t)*4)*C(t-j)/3,9,9)

Wait, 2 more characters can be shaved off so now it's 20 characters less than yours: for(x.globalAlpha=.3,j=900;j--;)x.fillStyle=hsl(${j-t} 99%50%),x.fillRect(960+j*S(t+j),540+j*S(t)*4*C(t-j)/3,9,9)
