    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, might be cool to allow for #4525 syntax to automatically link to the dweet

I see "Jan 1, 2018 7:39 PM" the date of post. Is it ok?)
u/sigveseb

That's the trick used to sticky the post :D the ranking is based on a combination of date posted and number of awesome. Future date == stickied post :D

(cleaned is referring to some slight blockiness on the right side of the animation, not the code. My code is much uglier :P)

Neat! TIL Javascript accepts python notation for exponents.

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.
