    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.

Oh nice! You added forward movement
u/iverjo

Great remix!

u/katkip

instead of that let you can use i=4e3,j=s=0
u/pavel

The let is only there for performance to use up free chars. j and s don't need initializing. But i at 4e3 cant do 60fps without let on my machine.
u/pavel

Can just do i=2e3 if you are remixing and need chars
u/katkip

oh, i understand
u/sigveseb

Sweet!
u/sigveseb

very nice
u/gambit

hi im new! can you explain me "c.width|=0" what does it do? thanks
u/DataMeta

Welcome! It's a shorter way of clearing canvas pixels/state. Can be chained like so: for(c.width|=n=i=256;i--;). It can't be done here because we must clear the canvas before scaling it
u/includeRubiks

so cool

u/ivylab

I don't even ... this is so cool, like a forest
u/pavel

This thing ((i&2)-1)*(2+i%7) takes so many characters. If somebody can figure out a shorter way to generate random-ish positive and negative numbers that aren't too close to zero that would be awesome. 7*C(i) is almost perfect but gets close to zero so you'd have trees on the path.
u/pavel

Oh! 3/C(i) works well here, but has no bound which will be an issue in other contexts.

I originally felt a little ashamed to post because the distribution of dots is not uniform, hence "dirty", but your kind comments have reminded me that nobody really cares. Indeed, bugs like this can even give an image more character than perfection would. Thanks! 🙏
