    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.

That's a really clever illusion, love it
u/magna

Heh, thanks! Brought it down to 123 chars in hopes of adding occasional mistakes like skipped characters / typos etc., but couldn't immediately find a way. In case anyone wants to give it a shot: https://www.dwitter.net/d/2522
u/donbright

u/Polyducks

Could you make a random function to skip odd spaces?
u/magna

It has to be a deterministic PRNG so that the places that are skipped are persistent. Otherwise, it would just look like a random flipping of characters. I thought about it, but couldn't immediately find a short solution.
u/Polyducks

That's a great point. Dwitter is such a mind twister!

u/magna

I was expecting this to happen one day...
u/magna

Wait. How the hell are you rendering the "ground"? I don't get it. Explanation please.
u/nystrand

It's the "(O" chars at the beginning of the code decreasingly scaled down from the large initial scale. I had to find a variable name that "looked good", - went with O which made coding confusing as it looks like a zero :)
u/magna

This is nuts!

Doesn't work on android, just see boxes with X inside :(
u/mxfh

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

Green, but the blips are harder to see

u/sfz

Increasing alpha helps see them, but makes the line sweep less cool

They are ninjas. Harder to see.

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.
