The Drepung Loseling monk artists created a sand mandala of the  Avalokiteshvara (buddha of compassion) mandala over a period of six days. The whole process was filmed and then the film was sped up.

"Hill set up two cameras in the room. One was an overhead camera that didn’t move during the six days; the other was moved every morning to get a different angle. Both ran continuously, shooting one frame every 30 seconds. When the last grain of sand was set, the monks didn’t spend time admiring their handiwork. Within about an hour, the elaborate art they had spent days crafting was carefully swept away during a ritualistic ceremony. This is normal practice, Rigzin said; it is done to symbolize the impermanence of life."
