Impressive is a program that displays presentation slides. But unlike OpenOffice.org Impress or other similar applications, it does so with style. Smooth alpha-blended slide transitions are provided for the sake of eye candy, but in addition to this, Impressive offers some unique tools that are really useful for presentations. Creating presentations for Impressive is very simple: You just need to export a PDF file from your presentation software. This means that you can create slides in the application of your choice and use Impressive for displaying them. If your application does not support PDF output, you can alternatively use a set of pre-rendered image files or you use Impressive to make a slideshow with your favorite photos. This requires PyOpenGL, pygame. pdftk is optionally required for retrieving PDF metadata (page titles, hyperlinks).
