Although I suppose a coffin is a pretty dark symbol, I really like the way the light is coming into this room, making everything so bright. Information from the sign:
"Coffin: 2005, Tieli wood
Made of wood salvaged from dismantled temples of the Qing dynasty, Coffin resembles a set of furniture consisting of a table in the form of a bent casket, with two long benches on both sides. By designing furniture for the living in the form of funerary objects, Ai pokes fun at the meanings of life and death and our associations with daily rituals."
