Hey HN,
If you're like me and was unaware you could have SVG emojis, here's a client-side tool to make a simple one. Just open your emoji picker, save the SVG, and use / modify as you please.
(I'm aware there are equivalents of this hanging around, this was just a day project. I'd recommend https://emojifav.com/ for this, but slicker. Only downside with that one is you have to unescape the data/svg it gives you if you want to edit it, e.g.: if you want to use media queries)
