    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.

I brought it down to 94b. for(x.reset(i=4),x.fillStyle='#d22a99';i--;)x.fillRect(600+i*150+S(t)*650,600+S(t+i)*32,90,90)
