    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.

just replace 𝘼𝙋𝙀𝙍𝙏𝙐𝙍𝙀 with Aperture. Which also is a bit heavy on the byte count.

Didn't know yours when I did mine (https://www.dwitter.net/d/6216), but yours is waaaay better than mine - I tried to do the dots in the radar and couldn't figure it out. :) BTW, kudos for using the "space" inside the x.beginPath call, great idea!

I thought the characters were underdeveloped but the effects hit the spot!
u/joeytwiddle

I was really confused why some of the lines appear softer than others. Finally realised it's because the canvas is scaled down

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

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.
