The sculptural atrium skylight shown here seems surprisingly restrained for Frank Gehry - the twirly bits happen outside the frame. Designed in collaboration with engineer Jorg Schlaich for the DG Bank Building in Berlin, it is one of the buildings that features in the Gehry exhibition currently at the Guggenheim Museum in New York. The exhibition runs there until 26 August and then moves, appropriately, to the Guggenheim in Bilbao. It will run there from 29 October 2001 to 3 February 2002. A handsome book has also been produced as the catalogue to the show. Called Frank O Gehry - The Art of Architecture, it is written by Jean-Louis Cohen, Beatriz Colomina, Mildred Friedman, William J Mitchell and J Fiona Ragheb, and is a Guggenheim Museum Publication, distributed by Harry N. Abrams. This is the chance for a thorough assessment of Gehry's work.
