    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.

Metamatrix

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.
u/scottglz

The clumpy crap is my favorite part

love the three d. i changed 'filltext(0 to filltext(i and went cross-eyed trying to figure out the pattern
u/sfz

Haha probably easier to figure out if you reduce the initial i to 6 and bump it up by 6 til you hit 44
