This page contains links to various presentations that I've given to classes.  My presentation style makes these presentations may be only marginally helpful, but I've gotten enough requests for presentations from students that I've decided to share them.  Most of these presentations of licensed under the Creative Commons Attribution Non-Commercial Share Alike license.  Slides are always provided in Adobe PDF format, but you'll lose any animation in the slides.  Some slides are available in OpenOffice.org ODP and Microsoft PowerPoint pptx formats.
