Some backstory:

I'm a big fan of research on normally condemned by society stuff.

Years ago I used to be actively interested in MAPS, an association focused on MDMA-assisted therapy (but also much more, check them out they're cool people), they had small websites (roll/tripsafe.org) with lots of precious information on damage control and research-baked ways to take stuff safely.

On one of these websites, there were a lot of links to cool WebGL stuff. They were really rudimentary 6-8 years ago, so over time they got replaced by Silk, which lets you draw with cool effects (by default mirrored bezier) - man this stuff is awesome lol, I hope I can find more links like this.
