"Soundgarden" (53x46x11) is a kinetic wall sculpture with a steel ball that starts at the top track, and by gravity follows a path over a variety of musical tracks and chimes. Everyone smiles when they see this one in action. You must see and hear this one to appreciate it. A similar sculpture can be commissioned for $6000. Motorized versions are also available. "Soundgarden" is now in a private collection. Click here to see a video clip.
