Yeah, they totally stalled out man... right around when Lloyd Khan  
came out with "Smart, not Wise" and so on... the industry has been  
muddling along in the margins, not taking over the world.

Part of that, I think, is slavish adherence to the hemisphere. With  
modern 3D design tools and CAD/CAM cutting equipment, it should be  
pretty easy to design dome structures which fit on square lots  a lot  
better, which have steeper walls and flatter ceilings and so on. Yes,  
there's a trade off in strength as you move further from the  
spherical line, but when you're overspecified by a factor of 10 or  
100, you can trade off some strength for other functional factors.

On roofing - how do you find Wil Fidroeff's technology - cement board  
covered in an elastomer from AFM (makers of SafeCoat paints)? I used  
to work with Wil - his T-beam geometry is extremely clever, giving  
very fast construction times, and the six way double compound miter  
joint is nothing short of genius...
