    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 love how this might look like the floor is sloping, or it might not. So trippy. It would be nice to avoid that flashy bit at the top though. Maybe in a remix?

I challenge someone to combine the two, golfing that is gonna be a doozy
u/z3vin

i love this can you explain: z=50+~~(i**2/80), specifically ~~ and **
u/nonce

~~ is Math.floor() and ** is Math.pow(), I do not understand why you need to floor? Why do you need an integer z? Also i*i is 1 char shorter than i**2 so you could shorten it to: z=50+i*i/80 am I missing something?
u/nonce

FWIW you can have a non integer font size
u/nonce

Golfed a bit, removed the pines (they are evergreen) and added a season: https://www.dwitter.net/d/2361 (autumn)
u/Jenky

Totally missed that, and didn't realise fonts could have floating px. Nice remix, too :D
u/sfz

floating px makes the rendering much slower but it's doable with a reasonable amount of entities
u/nonce

@sfz what about floating em? What is the perf like for that?
u/aemkei

Nice one! Really love the style.
