[CentralOH] My presentation files, video, docs

[Eric Floehr]

I've put the files from my presentation last night on github here:

https://github.com/efloehr/cohpy-oct2013

This presentation was an introduction to Python image processing using PIL
and matplotlib. It also talked a little about some nifty Python features
like the enumerate built-in.

You will need PIL, matplotlib, and ImageMagick (at least on Linux) to run
these programs.

For PIL, I would recommend the pillow fork, as it is the more maintained
version.

To make a movie out of the individual images generated, I ran ffmpeg with
defaults:

ffmpeg -i done/%d.png movie.mp4

The movie shown in the presentation can be viewed here:

Matplotlib, for graphing: http://matplotlib.org/

Built-in Python modules os, os.path, and fnmatch:
