bernardodias:Frei Otto came up with a great solution for large span coverings. The use of anticlastic (saddle-shaped) curves allows the membrane to undulate across a large area, and also provides for rainwater collection points in all of the depressions in the membrane. These pictures come from the book: "the work of frei otto", MOMA, 1972 -- source link
