I recognize this (really neat) video has but a tenuous connection to medicine, but I believe the mission of the Blast lab at the Imperial College gives us (some) license to post it here:
Blast Biomechanics considers the behaviour of the human skeleton under high impulse loading (such that is seen in a blast environment). Our interest in such behaviour stems from the ever increased casualties due to blast from recent conflicts.
Enjoy.
