I'm working in a new pmpd version that include the new pmpd2d~ and pmpd3d~. Nothing important change for the rest.
pmpd source are on my github :

You will face problem with spring~ and ball~ because of buffers, you better go for spring and ball.
and since a spring should also include damping element, let's call it "link".
And the ball have a null radius, they usually are called "mass" in the physical modelling world. (I don't know why SC try to be original and change the naming convention usually used)
So, this look a lot like pmpd, and after working with if for more than 20 years, I can confirm that this is very fun!

it's the masses that move!
