    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.

Hey! Just a heads up; I removed your speech synthesis dweet, as it was on an infinite loop and autoplaying. If you can post in a way where it doesn't autoplay feel free to repost it. For reference this was the code: t||(s=speechSynthesis,o=new SpeechSynthesisUtterance("god"),o.pitch=9) c.width=2 a=t%.7*10 a>.01||s.speaking||s.speak(o) x.fillRect(0,2,a,a) . (Yes, we could use a better moderation system than leaving comments on other dweets ^^). Cool dweet btw, keep it up!

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!

Changing the callback to "x.fillStyle=hsl(${d++*25},50%,50%)" turns it into an abstract art generator :)
u/yonatan

swapping PI/2 for PI/5*6 gets you pentagrams :)
