Bruce, the Presentation Tool is for people who are tired of fighting with presentation tools. Presentations are composed (edited) in plain text files (see the HOWTO). In its basic form it allows text, code, image, interative Python sessions and video.

It uses pyglet to displays via OpenGL and handle multi-head (the most common presentation setup) so you can have the presentation displayed on a projector while your laptop displays the original presentation source shown alongside (showing notes and animation or presentation cues).
