Harry Bertoia's sculptures

This is an art installation created by Harry Bertoia, it's basically a room full of sculptures that are made out of long, straight metal tubes.  When the sculptures are touched the tubes clang together like a chime creating an interesting noise.  During the course of the video he walks around and strikes several of the chimes, each creating vastly different sounds.  The result is what sounds like ambient music, with so many chimes reverberating at once.  He even has a few gong-like structures in the room which create other distinctive noises.
