As far back as I can remember, I've always thoroughly enjoyed giving talks. My current process involves making the slides with Beamer, then annotating them with LectureNotes, and combining the two using PDFtk.
Here are the slides of most of my appearances, in reverse chronological order; the number of slides is enlarged.
