    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.

I love that there is so much going on in its 8bit aesthetic! Wouldn't mind this becoming a new trend!

You can now record #GIFS! Try the record button. Note that processing takes some time, so I recommend trying a very short gif to begin with. Suggestions and feedback welcome. Thanks to u/BalintCsala for the implementation of gif recording!

u/lionleaf

(Note that gif processing happens in worker threads, so you should be able to switch tabs while waiting)

Hi Joey. Beesandbombs is cool. I tool a look at his animations and the code that generates them at github. Very cool. Still his stuff would be require many hours to reverse engineer. Your effort to move one his animations here is nice work. Thanks for bringing him to my attention.
u/joeytwiddle

I sometimes post his tweets in the Discord channel, as inspiration for dwitterers with dweeter's block. Agnes posted a prototype and we hacked away at it. :D Let's keep sharing the fun ones!
