    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 :) Better colors than mine

By saving golfing 2 characters I managed to make the twister bigger:

c.width=a=2e3;for(i=2*a;i--;)p=S(t)*i/a+i%4/.637,d=C(p)-S(p),d>0&&x.fillRect(a/2+199*(S(p)+S(t)),i/4,199*d,1/(d+1)),x.fillStyle=R(i/9,d*a/8)
u/iverjo

A little more movement: c.width=a=2e3;for(i=2*a;i--;)d=C(p=S(t)*i/a+i%4/.637)-S(p),d>0&&x.fillRect(a/2+199*S(p)+399*C(t),i/4,199*d,1/(d+1)),x.fillStyle=R(i/9,d*a/8)
