    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.

played around with it a bit... c.width|=0;x.font='6cm Arial';x.fillText('🏀',870,800+S(a=2*-t%3.2)*500);x.ellipse(1030,850,99+S(a)*60,10,0,7,0);x.fill()
