1. (easiest) Use a ripples normal along with Chris Colefax's texture
tiler macro 

2. (harder) Use an average of 10-20 randomly displaced (in the plane)
normals using the spherical pattern with a high frequency and a repeat
warp set up so that it does not intersect the pattern edges

3. (easy, Superpatch reuqired) Use an isosurface normal

4. (has its drawbacks) Rob a bank (you only need $3600) and then ask
Lance what to do :) "MAX.....3.0.... mumble.....mumble... yeah
kewl..... mumble ......anisotropic....mumble..... shading.....
nah...it's... cheap.....mumble....." etc, mumble <grin>
