I found this amazing installation on Pinterest and love it! It's designed by Gerda Steiner and Jörg Lenzlinger. It's called the Falling Tree and it was created for the 50th venice biennial in 2003. It was housed in the church of San Stae on the Grand canal, Italy.
visitors lie on a bed, above the doge's tomb, in the middle of the church and watch as the installation merges itself with it's surroundings.
I just love how the objects don't just fill the space, but seem to be a part of it. Oh how I wish I was in Italy in 2003!
