Currently having fun with:

* tack.pics - free online tool to mark points and polygon regions on images.
* 8bitretro.games - bringing back the good old days of gaming
* whatsmyip.net - because sometimes you just need to know
* feedfabrik.com - RSS Feeds at your fingertips

Also sharing code with the community through npm packages like barva <npmjs.com/package/barva> for color manipulation.
Always tinkering with new ideas. If you're working on something cool, I'd love to hear about it!
