Of course not (there is so much stuff ;-), but
the students made good use of VPython and also VTK/MayaVi was well
recieved.

So the bare minimum might be python+numpy/scipy/ipython/Vpython
(+any windows specific stuff?) + maybe VTK and MayaVi

OK, some in our group have much better knowledge about
windows, so I will ask them to test this approach.

I see - could this somehow be turned into a community effort?
Surely it is a non-trivial task - in particular the monolithic
structure of an all-in-one download package seems to make
upgrades of individual components difficult.
Would something like some super-installer,
calling the individual package installers be possible?
(or does anything like a package management system for windows exist?)
You see, I don't know anything about Windows, so I better
shut up on this ;-).

Many thanks, Arnd
