    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.

seems nice and fast for animations.. e=144;d=new ImageData(w=c.width=255,e); for(i=w*e;i--;){ c=S(t)*(i%w)**2+C(t)*(i/w)**2; d.data.set([c%w],i*4+3)} x.putImageData(d,0,0)
