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%

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

The joke was going to be that everything turned sepia (#7F462C) after it stops but I couldn't find any way to get that below 152 characters. I'd be really impressed if someone found a way.
