A little while ago there was a discussion of a maze pattern.
Well, the attached is a single CSG object, not a pattern, but it was
my first experiment with macros.
Worked out pretty well, but the parsing time is a tad high.
----------
Resolution 512 x 384
Time For Parse:    0 hours 22 minutes  57.0 seconds (1377 seconds)
Time For Trace:    0 hours  9 minutes  54.0 seconds (594 seconds)
    Total Time:    0 hours 32 minutes  51.0 seconds (1971 seconds)

Official POV-Ray, on a Pentium III, 550 MHz, 128 Meg RAM
----------

Note that there is exactly one true path through the maze.

The macro takes parameters for number of rows and columns, and
a seed value for the random number generation.

Still need to work on:
- Splitting generation of data and creation of object, using a file to
store the data (to reduce parsing time between rendering attempts).
- Options for wall thickness and height, and for path width.
- Expanding my algorithm for a hexagonal shape (no promises!).

Any interest?
