I'm pretty tempted to write a C++ .obj parser -- I've written a few python ones in the last few years to test out parsing algorithms since the grammar is simple and there's plenty of example files out there. The last one (testing my py3k+metaclass conversion of spark.py, the earley parser from the python source tree) was something like 100x slower than Campbell's handwritten one but that's to be expected from a slowish algorithm that can parse pretty much any grammar you throw at it. Been wanting to play with Boost::Spirit so maybe I can knock out something fairy quickly using my (mostly complete) grammar from spark.py.
