It looks nice, but the brick pattern, like other color list patterns, is
not well suited for isosurfaces because of the infinite gradient problem.
I think one could make a special continuous isosurface function similar to
the brick pattern to avoid this.
The mortar looks a bit too 'glowing' maybe reduce the ambient component.
BTW, what exactly is Jeff Lee's technique?
