User dolesistheboss uploaded nice HD video, showcasing PhysX Destruction demo from Jen-Hsun Huang GTC keynote. Description says:
The goal was to try and construct a wall similar to how it may be constructed on a movie set and break it apart in a realistic manor in real-time. In this scenario we chose to throw ragdolls at it to fracture and splinter bits and pieces off.
The demo uses PhysX 2.8.3 and a beta release of APEX Destruction.
