"Here at Blur we've developed a way to integrate the Python (http://www.python.org) programming language into the 3d Studio Max application. By mapping the basic MAXScript value class to the basic Python PyObject class, we're able to expose MAXScript functionality as a Python module. All maxscript methods are available using the mxs module and run the same way as they would normally in maxscript, only using a pythonic syntax.
For faster development, we've also integrated the PyQt framework to allow development of Qt applications instead of MAXScript rollouts."
