You should definitely try to contact Peter Pearce, formerly president of Pearce Structures in Chatsworth, CA., and an author of books on structural design. Peter was a protoge of Bucky Fuller, and I met him at Calarts in the early 70s when he was associate dean of the design school there. He left and formed a number of companies over the next two decades, applying his mathematical space-frame and soap bubble ideas. In the late 70s he created huge children's playground structures based on soap-film polygons. Pearce Structures was the architect of the Biosphere in the 80's. He has left that company and is doing consulting work. I don't have his current phone but you might try Pearce Structures at (818) 998-2811. If that doesn't work let me know, as a colleague of mine has worked with him recently and I can get the number.
