Had a similar idea and built a prototype for it.

#5Very cool! nice to be able to export json too

#6Very cool! Interesting how the choice of solver affects the solution. Euler doesn't handle misbehaved equations very well. You can see this in the Helix setup where the bodies just fly off.

Occasionally two will tight spiral off together.
(Experimentally 5/250, including 1 cool wide, almost flat spiral.)
