I was reminded of this last week on a visit to Manhattan, when I stopped by the Guggenheim Museum: another iconic place, temporarily transformed in a way that I think will be hard to shake. James Turrell, an artist I especially like who works with light and volume, has taken as his canvas the legendary spiraling rotunda that constitutes the interior of Frank Lloyd Wright’s 1959 building. You’ve got to have some serious chutzpah (or substitute your foreign-sounding noun of choice…cojones? hubris?) to fiddle around with Wright’s legendary spherical volume, with its gently rising rampways that culminate in a spider-web dome window.
