[CentralOH] focus for numpy/scipy presentations

[Neil Ludban]

At the last cohpy meeting, several people wrote down numpy and/or scipy
as desired topics for future presentations.  These are very broad and
easily turn into boring overviews of python for matlab people.  Does
anyone have requests for a presentation on a specific scipy module,
digital signal processing topic, or even an idea for a project that you
heard numpy/scipy would be good for but not sure how to get started?
