If you're ever in Cambridge, come see what I think is his last commission which is this great terrazzo. So lovely and bright during the rotten winter.

It's much more vast than the photo shown. It's 15 squares of 18 square feet.

Here's another picture of it (again, click to enlarge).

Wasn't sure what to think of it when I saw the initial drawings but wow, it's very impressive now that it's in there--and it took them 4 months to install.
