I haven't seen a lot of curriculum writing making use of VPython's nifty 2D plotting capabilities. Sure, other packages have more bells and whistles, plus 3D plotting of various kinds, but then VPython has all these other advantages, including a rather streamlined API.
I'm looking forward to the new release. Currently, installing VPython on Linux and/or Mac is not trivial. Better installers would go a long ways towards making this a more usable add-on for Python.
Free cone day at Ben & Jerry's, just got a text message. Gotta run.
