Running pdfpc in StumpWM
pdfpc is a fantastic application for presenting PDF slides, including perhaps especially those produced using LaTeX Beamer. It creates two (full-screen) windows, one a presenter viewer which shows the time elapsed and a preview of the next slide, and one the presentation view which is what is shown to the audience. It also has a bunch of other cool features like being able to draw on slides; highlight areas of slides, &c.
