    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 feel like this might open the floodgates with people making use of the globalCompositeOperation setting... if only it was shoter :-p

You take a 30-40 char hit depending on which mode, but there's still room for fun :D

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.

Love it! did a quick remix with the Russian П in sans-serif just to see what a tunnel might look like: https://www.dwitter.net/d/2332 and got a weird thing happening on the floor. :-)
