@Francis,
Ha, I just checked in to give the answer and get this started again, and you've done it already, Francis.
Here's a link on the projects of Michael van Valkenburgh, an interesting designer - his photos are much better than the one I posted but I couldn't link the one of the Ice Water bluestone sculpture at the time. I heard him speak at UCLA in the mid eighties; like some of his work, am irritated by some of it, but his designs are usually at least interesting.
