    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.

#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.

.618 is an approximation to the golden ratio. Putting .5 == 1/2 will create 2 spokes. Similarly .6 == 3/5 will create 5 spokes.

You can save 1 character by putting arc(650+250*i,700-i%2*434,r/2,z=i*2.095,5.235+z) in the for loop before stroke()

The graph r=theta spinning around the origin. 65 characters to play with, so there's lots of remixing potential. Try messing around with the trig functions, it leads to some fun results

Go fullscreen, stare at the center for 30 seconds, then look away from your screen (e.g. look at your keyboard). #opticalillusion
