I don't necessarily look for a team, but I do have a tip: if you want to run some physics sims, use matter.js. It's a handy little library that handles constrains, collisions and so much more for you.
Woah, thank you very much for sharing! Looks really solid.Are you joining the jam? Just read your previous post and looks like you're going javascript route as well :)
Always happy to help! I will indeed be joining the jam, and I'm going to use p5.js for all the drawing related stuff. Good luck and have fun!
