GreatPyramid.jpg

  I'll have to render a more detailed shot so one can tell,
but this Lego Minifig Scale Great Pyramid is 401 bricks high
and 800 studs square at the base.  It's just a shell but it
still contains nearly 1/3 of a million Yellow 2x2 Bricks !
  It was a design study for an actual pyramid that my wife 
wants to build.  We decided that we can't build this one because
it's close to 12 feet high and wouldn't fit in our house : (
  It took my Athlon 1 GHz computer 4 hours to parse and render
the povray file which is 15 megs in size.  I wrote a small VB
progam to generate an ldraw .dat file of a single wall and then
used four of them as subparts in the main .dat file.  I cheated 
and commented out two of the four walls in this shot to speed
up the rendering.

  This one's much bigger than the great pyramid model (1024 studs
square at the base) but it's much more open and uses a lot less
bricks.  The four sides of the pyramid are serpinski triangles
and are recursively defined so that the dat files take up only 4k
of disk space and the .pov file is only 12k.  
  It rendered much faster than the great pyramid, too.  It only took
46 minutes.
