    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.

With help from the code golf team, we were able to get the matrix crawl to have a black background :D

u/sigveseb

would be cool to have some sort of feature in dwitter to group effects into categories. Here's my take at matrix! :D d/4922

Tags would be helpful for grouping effects

u/donbright

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.

Maybe someone can add a black background, but I'm not good enough at golfing down js code to this. #matrix
