Yesterday Havok announced that the famous physics engine is finally free(with some limitations obviously). The No-Charge Havok PC download is a binary-only bundle that includes all of the standard features and functionality of both the Havok Physics and Havok Animation products. The download includes Havok SDK libraries, samples, and technical documentation for software developers; as well as Havok"s Content Tools for preparation and export of physical assets and characters directly from recent versions of popular 3D modeling and animation tools.
