These are notebooks I used during an Introduction to IPython Notebook talk I gave for EAST Knowledge (http://eastknow.org). I used IPython Notebook v2.0 for the talk, but I don't think I used any advanced features that require a particular version.
These easiest way to use these notebooks is to install IPython Notebook. Then execute:
$ ipython notebook
Out of the directory where you have placed these files. This will also work on Windows.
