    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.

Nice aemkei, thanks!

This is amazing. I'm brand-new to coding and very new to Dwitter; how on Earth do all of those symbols and letters code for a picture of the Earth?
u/RomanW

Hi oldspork! The magic happens with the function charCodeAt. This function gets the numeric value of one character at a time. Since these are UTF-16 characters, you can get 16 bits of information in one character.

Is there an easy way to make these kinds of things? (specifically how the data for each pixel is stored)
u/dsamarin

String.fromCharCode.apply(null, new Uint16Array(34).map((r) => Math.random()*0xffff))

Basically a UTF to binary decoder. The variable z is the zoom level.

Nice! What's in the QR code?

Sweet! Of course, I saw your work *after* I posted. I was going to try and unpack your technique today, so I'm pretty happy that you did this remix

Each line segment can have 16 directions (4 bits). The 100 line segments are encoded in 25 UTF-16 characters. Very ego-centric result, i know, i know :)

u/sigveseb

Ooh, very nice indeed!

You've reached the end.
