yep, you are absolutely right! The C# project hasn't moved anywhere in the past 6 months.
Now I've been working a bit in Python and using VPython for visualization. There's still a lot to do on drop-cutter, and the next thing I want to do is called 'push-cutter' for calculating waterline toolpaths.
I recently found shed skin, a compiler that translates Python to C++, if people want to use the CAM-library from C++ programs (+ you get a 20x speedup).

Another interesting development is the wildcat CAD program:

if anyone is interested in helping out, let me know. The first thing would be to get the existing functionality in C# ported over to Python and then work on some bugfixes. Then start on new cam algorithms.
