You may be interested to take a look at a couple of the submissions on the 
Object Collection at http://lib.povray.org/searchcollection/index.php - 
Search for 'Grid' and select 'Partial word search '.

The GridLines texture uses an approach similar to the texture tutorial you 
mentioned.
The ShapeGrid macros give you objects similar to the one you've defined, but 
for a range of different shapes. You can use these objects as you have done 
in a CSG operation, or you can use them as textures by using the object 
pattern. Both techniques are illustrated.

The trace function has already been discussed. I just wanted to add that you 
can often circumvent the problem of concave indentations by moving the point 
from which the trace starts as the scan progresses. Effectively creating a 
scan path through the object. Clearly this requires some prior knowledge of 
the shape, but it can then cope with far more complex scans.
