    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.

Example of looping with recursion, trailing off as time goes by

u/joeytwiddle

For the first 9 seconds it calls u() 250 times per frame (on average), after that just once per frame

Looks like these M.C. Escher lithographies, I love the feel of it!

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!

Sadly not. Still on the wrong continent. My crew too. But I'm tuned in.

Too bad :( I actually flew in from a different continent; you need a stronger excuse!

Hehe well I'm also trying to save the oil. Although I'm realising it's useless :(

Smooth banana

We need x.beginPath() to draw filled circles, so instead this draws lots of hollow circles
