I was very excited to see a new installation of some large scale sculptures on the lawn connecting two of these buildings. I don't know the tenants, but I'm guessing biotech. Interesting, too, that it's right down the street from the Olympic Sculpture Park.
One of the pieces (Source, mounted on the concrete platform)) is by Canadian sculptor Sorel Etrog (Romania 1933). The others are unidentified.
Now it turns out that Des Moines, IA, loves sculpture, too!
