To view these examples, you must start up an IPython Notebook server via the folowing command (in the current directory):
ipython notebook
Then, you should be able to load the notebooks and execute them interactively (push shift-enter to execute a cell)
You can also view all of the notebooks (non-interactively) via github at:
