    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.

with(x)for(c.width|=q=700;q--;)fillStyle=R(q,q-100,2*q-100),beginPath(),arc(960+(z=400-q)*C(t-q),540+T(z)*z,1.01**q+5*C(t)+4,0,9),fill() - a slight bit thicker, butfixed your errors
