    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.

You can change the number '55' at the end to give a different pattern.
u/ximavus

If you remove the %55 entirely it fills and leaves a internet logo

Kyle's Ant

This one was hard to compress. It was originally rainbow coloured, the camera moved with it, and the trail slowly disappeared behind it, giving a more interesting pattern.

Fantastic. That could be a real old photograph of something.

Finally a new front page "top | year" dweet! I personally don't like the default. I think it should be the default for not-logged in users. And logged in users should be able to define which to default to in their user settings.

#confetti remix! Had to go to squares to squeeze color in, but should be possible to golf back to circles

u/BalintCsala

You don't have to close the hsl function
u/redactedhoptional

You can use a template string in the color string, so hsl(${9*i},99%,50%, it saves 1 character. You could also make it translate(960,540) so it is correctly centered.
u/redactedhoptional

Also also, you can remove fill(), and round the -3.88 to -3.9 to save a character.

You've reached the end.
