Some of you are working with shadows for the current assignment. You might find the following example inspiring:

In his work The 7 Lights, artist Paul Chan makes use of light and shadow, through digital projection.
“The Lights create a vast image of cyclical destruction and rebirth, spread across floors and walls like light falling through windows. Structured over the course of a day, each of the Lights begins peacefully, with the warm colors of dawn. Slowly the atmosphere changes: silhouettes of objects rise up through the air and are dismantled by obscure forces, while human shadows plummet towards the ground.”
