This video simulates the collapse of a 15,000-foot tower of 25,000 barrels of oil using the Unreal Development Kit, a video game platform. It was made back in May. According to the current estimates (a spill rate of 60,000 barrels per day) this tower represents about less than half a day's worth of oil.
