Hey 2p2,
I've decided to make a downloadable version of the
ev++ Variance Simulator. The source code is also available (Python, requires wxPython, numpy & matplotlib).
The executable version will only work with windows, but the source should run on Windows, Mac & Linux (you'll also need a c compiler to create a little dll). For more info please go to
the download page
Quick screen shot:
I have tested on Win 7/Win XP and Linux but please let me know if you have any troubles and I'll do my best to help out.
Oh and it's free but donations are always appreciated!
