Latest Plucky Adventures...
The wood half-rounds and balls I ordered from these folks (http://www.craftparts.com/) arrived, as did some 17" heavy-duty cable ties. I put together two hubs and an edge section last night and it looks/feels pretty good. I hope to do some additional work with the pieces this weekend.
As I've been working with this stuff I keep thinking that a similar structural system could be implemented using bamboo in place of the PVC, and hemp rope in place of the plastic wire ties. This would give you a completely organic structural system, using materials that would require only simple and low-energy processing and that are locally available (growable) in most of the world. Interesting.
