thi.ng is great and should really get more attention. The packages have a very clean and atomic structure, you can easily pick one or more and use them in your project.

fun fact: you can reach each package from a https://thi.ng/PACKAGE short URL, e.g. https://thi.ng/color.

I started using the thi.ng collection a couple of years ago when I had more time for creative code sketching (https://guidoschmidt.cc/sketchbook, father of two now, with full time work + family its hard for me to find time and motivation at the moment. Hopefully will get back to it more in the future), still only scratched the surface yet.

https://www.creativeapplications.net/people/karsten-schmidt/ has a great history of Karsten's work. Also worth checking out his mastodon profile: https://mastodon.thi.ng/@toxi
