Notice how the fluorescence of Frank Gehry's new Lewis Library in Princeton pops in tandem with the buds of Spring. Dazzling contemporaneity. Enjoy it now, because when graduating Princetonians come back for their five year reunion, chances are the colors on the Lewis "Library" (there's little room for books) won't be so bright; and it may take a little more than Windex to keep this glass clean. (The Louvre, after much frustration, resorted to robots.) Gehry's new building is a visually provocative, downright sculptural creation - snazzy study space with expensive chairs and ample refreshments. But for longevity (and dryness), my money's on Dimitri Porphrios' Whitman College.
