I was bored, and the recursive torii post got me thinking of recursion, 
so I made a simple macro that draws the Sierpinski Pyramid.  Before I 
made this, I didn't know POV-Ray allowed macros to call themselves. 
This particular image is built from 78,125 pyramids, each made using 6 
triangles, for a total of 468,750 triangles, all wrapped up in a single 
mesh with some radiosity, sky_sphere, and a plane tacked on.

(NOTE: I did some searching around...some places show the Sierpinski 
Pyramid as having 3 sides on the base, others with 4.  4 was easier to 
implement, so I used that.)
