    Nice!
  • u/vain
    Btw... shouldn't "[i%5]" be "[i%6]"? Else you could save 1 char. :) What do these three points mean you used here: "fillText([... ,'" ?
  • u/BriSeven
    Whoops, you're right. The ... is the spread operator, it splits the string in a unicode friendly way, and assigns the individual characters to the enclosing array literal.
  • u/BriSeven
    @vain do notifications work on dwitter?
  • u/BriSeven
    the ... next to the string is actually a special case. more generally it works on anything that implements the "iterator protocol" which is lots of stuff, but mostly arrays and array like things.

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

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

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