FOAM - Actionscript 3 2-D Physics
Looking for a fresh new actionscript 3 2D physics engine? Check out FOAM (Update: also check out a much more in-depth description on the generalrelativity blog). From the project page:
FOAM is a two-dimensional rigid body physics engine written in ActionScript 3.0.
It is meant as an architectural and mathematical reference for developers interested in physics simulation in the area of game development or otherwise. It trades efficiency for modularity and extensibility.
