and matplotlib. It also talked a little about some nifty Python features
like the enumerate built-in.

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

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

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

The movie shown in the presentation can be viewed here:


Technologies introduced:

PIL, specifically the pillow fork, for image manipulation:
    Code: https://github.com/python-imaging/Pillow
    Docs: http://pillow.readthedocs.org/en/latest/

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

Built-in Python modules os, os.path, and fnmatch:
    os:      http://docs.python.org/2/library/os.html
    os.path: http://docs.python.org/2/library/os.path.html
    fnmatch: http://docs.python.org/2/library/fnmatch.html
