If you are not satisfied with the efficiency or PowerPoint or simply want your slides to be more interactive than they are PptPlex is the solution for you.
pptPlex uses Plex technology to give you the power to zoom in and out of slide sections and move directly between slides that are not sequential in your presentation. Pptplex overcomes the limitation of linearity in the presentation by changing the way we create slides to deliver them in a non-linear way in order to give a stronger impact to our audience.
It works as an add-on to an existing 2007 and 2010 installation of Microsoft office.
