Some 3D Cayley graphs maybe? Not much interactive though.
sage: W = WeylGroup(['A',3])
sage: d = W.cayley_graph(); d
sage: d.show3d(color_by_label=True, edge_size=0.01, vertex_size=0.03)
sage: W = WeylGroup(['B',3])
sage: d = W.cayley_graph(); d
sage: d.show3d(color_by_label=True, edge_size=0.01, vertex_size=0.03)
And in case you can run your demo with sage 4.2 and #8044 gets merged
in time:
sage: W = SymmetricGroup(4) # same graph as for A3 above
sage: d = W.cayley_graph(); d
sage: d.show3d(color_by_label=True, edge_size=0.01, vertex_size=0.03)
sage: G = GL(2,3)
sage: g = G.cayley_graph()
sage: g.show3d(color_by_label=True)
Cheers,
