Another edit of one of my old texture photos.  This one comes with a height map for parallax mapping, etc.  The test render is done in Blender Cycles, making use of the displacement map (so it should give you some idea what it will look like with parallax).

Random notes no one cares about:  Luminosity turned out to be a really good approximation for height here.  THe height map is just a desaturated version of the image with a median filter run on it to remove some of the really small bumps.  I think it came out pretty well.
