    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.

Well done! Try to change "v,32,32" to "v,32,.02" or "v,32,.05" or "32,.2" to archive some interesting effects.
u/KilledByAPixel

you probably already know but you can remove the hsl comas to save a byte hsl(${a/7} 69%50%
u/pavel

That does not work in Safari, the color will always be black.

1282675 encodes the 'turn right' or 'straight' orders in binary, >>f&!(f%1) checks them on frames when f is an integer.
u/tomxor

Satisfying, looks like a recursive "Bowen Knot"
u/leafyvez

so beautiful
u/rep_movsd

This looks like the traditional "kolam" that Indians traditionally draw in front of the house
u/rep_movsd

Changing that 1282675 makes different patterns

Oops, you have to flip X and shift it a bit, then it's -1
u/pavel

If you start with 0 and simultaneously replace 0 with 1 and 1 with 001 you will generate this sequence and bigger ones.
u/pavel

Similarly, if you start with 1s and replace s with s1s00s1s and ignore s when drawing.
u/pavel

I invented the second method. The first one I found by putting my hand-made small sequence into https://oeis.org .
u/CalSch

It's the command key but more complex

Number collector!! Click the screen to move the square 90 degrees clockwise. Collect the numbers. Don't crash into the edge of the screen or all your points will be lost. #interactive #game
