Been goofing around with some ideas for the decay round.  In the process I
came up with a macro that parses a mesh file and replaces it with cubes.  It
works recursively, so you can specify the level of recursion to get more or
less detail.  Anyway, here are two test images.  The first one is done
without recursion, and the second one is with one level of recursion.  For
each level of recursion, it subdivides each cube into a 3x3x3 cube (27
sub-cubes), then samples those points to see if they are inside the mesh or
not.

Me like!  The first is brilliant.
You could have used it the last round too ;)

What kind of meshes? .OBJ?

Nice! Would have made a good surreal entry...

How long does it take to parse & render?

Took about 3 minutes with no recursion, and about 10-12 with 1 level of
recursion.
