Recently, I haven't had much time to work on pybox2d. And when I say 'not much', I mean just about zero.
In any case, I know that there are probably a couple people out there that are anxious to try the new version but don't want to go through installing SWIG, compiling, etc. It's a pain, I realize.
The other day Fahri, creator of Mekanimo --- the only commercial product to use pybox2d that I know of -- asked me if I had a binary he could test of the new branch. I threw a simple Python 2.6 (win32) package together, and thought that the rest of you might like to give it a go also.
The library itself is contained in the archive, so there's no need to install it. The redesigned testbed examples are in there, and you can experiment with the new syntax to your heart's content. For any of the tests, simply run: python test_Web.py . You can also specify the (incomplete) pyglet or pyqt4 back-ends with: python test_Web.py --backend pyglet or '--backend pyqt4' for example.
I only ask that if you give it a try, please at least run python run_unit_tests.py and see if you get any errors. Also, please note that this is alpha-quality and does not have much documentation.
