His sculpture, Musical Fence, at the DeCordova Museum, is an all-time favorite of mine.
A lovely, whimsical work that you are supposed to whang with a stick!
It makes lovely muted chimes as you hit the aluminum bars that are sturdily held in place by a cement base.
The work is utterly simple and brilliant, and a huge inspiration to me.
