    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.

Managed to shorten this by 4 characters: for(c.width|=i=0,x.globalCompositeOperation='xor';i<300;i++)R=515*S(t+i/3e3*6),x.fillRect(960+R*C(t+i)-25,540+R*S(t+i)-25,50,50)

d/5673 is really cool to edit. most notably with how t is used in the trig functions; which functions are being used, and where they're used)
