#Minimal 3D plot, showing the sin of the distance from the origin.
#Python version 2.7.3
#Matplotlib version 1.1.1rc

#Code also works fine with Anaconda3 / matplotlib version 1.4.0!
#Code also works fine with CPython 3.4.2 + Scipy-stack-14.8.27.win32-py3.4 from
#   Christoph Gohlke's unofficial libraries:
#    http://www.lfd.uci.edu/~gohlke/pythonlibs/

#Code works fine with default Python3 + sciPy stack on Ubuntu Linux 14.04
# sudo apt-get install python3-numpy python3-scipy python3-matplotlib
