    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.

If you can't see both rotations, Slacklustre's GIF may help: https://www.reddit.com/r/illusionporn/commen…

Classic Slack #loading spinner (RIP release)

cool! also cool it's #compressed using the UTF-16 surrogate pairs method =]
u/joeytwiddle

It sure is! I gave your compressor a try.

This dweet was first attempted by BirdsDweet and myself in February 2018.
u/joeytwiddle

We never really finished it, so this is as far as it got. I publish it now, because Slack has now changed their spinner!
