    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.

wow @ u/danny@hille.dk i was working on something with similar output, but using x.lineTo ! i will share soon, but its over 140 maybe you can help me golf please : )
u/smtsjhr

clever x.clearRect trick! its like you are "erasing" what you intend to draw! ...and it seems interchanging x.clearRect and `x.fillRect' in your code looses the blur effect hmm!
u/smtsjhr

@ u/danny@hille.dk check out d/21499
u/danny@hille.dk

.fillStyle='#0001' sets fill color to black with a transperancy of 16% (this css shorthand hex color notation, denotates color in 4*8bit RGBA, it is in essence the same thing as the standard #RRGGBBAA notaion, but with less resolution) fillRect then fills the intire screen with that blackish color then clearRect is used to "paint" white squares (the main reason is so you only have to use fillStyle once) When the main loop runs again - the white squares are only mostly paintet (84%) over, which results in a kind of motion-blur/glow As far as i know, you cannot use this technique with lineTo since line uses strokeStyle to draw linecolors
