If you own a copy of PowerPoint (it comes with the MS Office Suites, like Office 97), or you have access to it, you should try creating a presentation with it. PowerPoint presentations can be used with PC projectors, they can be printed to overhead flimsies, they can be copied digitally to the web.
I won't go in to the details here. There are many manuals and books which cover the program in detail. My point here is that you should probably (for educational and professional purposes) own and know how to use a presentation software like PowerPoint.
