I'm fairly sure I will switch to Boost.Python for wrapping C and C++ extensions for Spineless. Boost.Python is much more actively developed than Pyrex, and supports C++. My only concern is that it could complicate the build process... but the decision hasn't been made yet, I'll review, test and benchmark it (and possibly other options) against Pyrex first, and figure how it would integrate to the Spineless setup script.
SWIG is definitely out, since it uses an additional Python layer for wrapping C++ classes, so it's much slower than other options.
Still no screenshots, sorry. I will give you a comb jelly instead:
