    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.

Hi. I'm a great fan of your work and I am trying to learn the dwitter wrapper, by studiing the "Dissecting A Dweet" and other texts you posted. But I must say it's difficult to start although I have some experience in Java script. I wonder if you could give me a pure JS translation of the following code you wrote. So I can compare the two of them It's the undefind sketch: for(x.fillRect(0,0,i=640,i);z=--i**.3;x.fillStyle=R(0,500/--z))x.setTransform(s=20/z,0,0,s,0,0),x.fillText(i!=1?''[1]:' 😱',i%z*99,t++%z*60)
