As for the brick, (which is changing slightly in the updated version), I 
do almost everything with isosurfaces.  The bricks are just slices of a 
cylindrical tube, and I subtract out a pigment function based on the 
marble pattern.  In the first version, each block had its own random 
cracked marble pattern applied to it.  In the new one, there is a global 
crack pattern that gets applied to the foundation and each block so 
there is consistency with the way the fountain is cracking.
