    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.

reduced it by about 15 bytes in case you want to try to do something else with the extra room: c.width|=0;for(i=16;i--;)x.ellipse(1e3+300*S(t+i/9),500+50*C(t+i/9),160*S(-i/2)+160,50*S(i/9)+5,1.6+S(t)/2,9,0,7);x.stroke()
