Metatrace is a C++ compile time ray tracer (as of the initial release, it is a whitted style one).
It is mostly inane stuff. except, maybe, that it's a nice gadget to test compiler performance and conformance, especially but not exclusively in the Template and Metaprogramming corner of C++.
It requires basic C++-0x support. To use g++, have at least version 4.4 installed.
