Here's a nice lecture by Carlo Rovelli on his development of Spin Foams with Lee Smolin. Great to see the intro to his lecture by Penrose:

At time 41:33, you can check out how space is defined as the volume around a vertex. Steve Smith and some others have heard me wax incoherently about the potential that spacetime is the dual graph of the spin networks in much the same way a voronoi is a dual to a delaunay graph.

    Can you point to what you think Baez was doing that seems similar to what Wolfram's doing?
