+rigid body dynamics.  It is fully featured, stable, mature and
+platform independent with an easy to use C/C++ API.  It has advanced
+joint types and integrated collision detection with friction.  ODE is
+useful for simulating vehicles, objects in virtual reality
+environments and virtual creatures.  It is currently used in many
+computer games, 3D authoring tools and simulation tools.")
