Springs connect 2 particles and try to keep them a certain distance apart. They have 3 properties:
- Rest Length - the spring wants to be at this length and acts on the particles to push or pull them exactly this far apart at all times.
- Strength - If they are strong they act like a stick. If they are weak they take a long time to return to their rest length.
- Damping - If springs have high damping they don't overshoot and they settle down quickly, with low damping springs oscillate.
NOTE: Documentation is only very slightly adapted to comply with the SuperCollider port. See the original by Jeffrey Traer Bernstein here...
