Tracy demonstrates how the moving mandalas work
Take a digital picture and students cut it out. There has to be something vertical behind them. Most choose a brick wall but others did trees and interior wall as well. Explain how a shadow would fall on the floor at an angle and go up vertical on the wall. Let them choose if the shadow was going to be large or small according to their idea. The shadow had to tell me something about the story. Perhaps their dreams, or nightmares, something they enjoy or maybe a hobby.
