Do you mean something like the twin-layer geodesics on
http://w3.one.net/~monkey
that David was working with? He's been making geodesics that have a
warped octet truss as the skin, rather than a single layer, in a hope to
increase the local strength and resistance to buckling.
If memory serves (been a while since I read the article) he generated
a 12F patch as a test...and it worked well.
