Physics-simulated demolition: a 30-storey tower collapses in 7 seconds when you fire the centre first

An interactive 3D physics simulation of controlled demolition: firing the centre of a 30-storey tower first makes it fall into its own footprint in 7 seconds, while firing one side first topples it into the street. The author says it is useful for game development; a stone from the roof lands in 4.4s vs 7s for the tower, since each floor must crush the one below.
