My attempt at construction of a paperclip model with interesting
topology.  I doubt you can really see from the picture, but it's not a
simple dome.  Opposite sides connect, but in one direction, the
connecting chains are longer than in the other.

I found this construction method less than ideal.  Paperclips not in
tension flop around and the joint connection is messy.  Talia had
small rings at the nodes so her joints were symmetrical.

My goal for this construction was to make a model with interesting
surface topology.  To construct the model I first draped long chains
from one side of the plan to the other, then linked the chains
together with horizontal pieces.  Unfortunately, that puts these
horizonal pieces in compression and that doesn't work so well with
these joints.  I'm going to dismantle this and build something else.
