    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.

NICE! you could zoom the ripples for a psychodelic wave like this for(c.width=X=64,w=30;X--;)for(Y=38;Y--;x.fillStyle=R(o=S(S(X/9*Y/9)+(Math.hypot(X-32,Y-21)/13-t)*5)*230,o*.8,-o))x.fillRect(X,Y,1,1)
u/danny@hille.dk

or pixelate, for some retro style, and mess with the colors: for(w=30,X=64,w=30;X--;)for(Y=38;Y--;x.fillStyle=R(o=S(S(X/9*Y/9)+(Math.hypot(X-32,Y-21)/13-t)*5)*230,-o,o))x.fillRect(X*w,Y*w,w,w)
