     In addition to Moore, Von Neuman and Margolus neighborhoods, the spatial, temporal (phase) and user connector extensions of CAM-PC provide for a large number of different neighborhoods. In this sense, a simple neighborhood is actually a selection of up to 16 of the 50 to 100 signals (depending on what you count) that are available.

     Another thing which seems to work very well is embodied in the Margolus neighborhood, for which different rules are operative at different points in the lattice, and even at different times.

     For any one interested in CA's in general or in simulations that require the conservatin laws of the Margolus neighborhood in particular I've managed to devise a method for duplicating all the properties of the Margolus neighborhood without the paritioning and without the block rules.
