    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.

i wonder if there is a way to mix this with Kalanchoe's technique from https://www.dwitter.net/d/1395
u/donbright

something like this r=Math.random t?o.push({X:480*r(),c:~~(r()*99),Y:0,ẏ:1}):(o=[]) c.width=480 o.map(a=>(x.fillText(String.fromCharCode(a.c++),a.X,a.Y+=a.ẏ)))
u/sfz

well, if you change the for loop to something like for(i=99;i>18;t+=i--) it gets rid of the clumpy crap on the left side, but I didn't figure that out until afte posting.

Continued fraction for the golden ratio, 1+sqrt(5)/2. #math #numbertheory https://en.wikipedia.org/wiki/Golden_ratio

u/taupelink

hmm, doesn't seem to work on iOS Safari
u/taupelink

to get it to work on iOS/MacOS, replace 2e3 with 1920 and 1100 with 1e3.
u/taupelink

* maybe it's a safari issue rather than an OS issue. * on my iOS device, that adjustment seems to work temporarily, but then the browser has to reload the screen. ¯\_(ツ)_/¯
