pptPlex uses Plex technology to zoom in and out of slide sections and move directly between slides that are not sequential in your presentation. You can arrange all slides on a stunning canvas and can zoom in or zoom out slides during presentation besides navigating in a non-linear fashion. You need not to go slide by slide, just double click any slide thumb on the canvas and slide will appear with smooth zoom effect.
pptPlex also lets you add live content from other Office documents(Word, excel) in your PowerPoint presentations. Live content means if you have added some excel sheet and source data gets changed, your presentation will always have the updated data as will read the data from excel sheet itself.
You can download pptPlex from Microsoft labs. You would also require to download and install XPS or Save as PDF add-in in order to use pptPlex on PowerPoint 2007.
pptPlex is quite easy to use and for sure it will add some seasoning to the way you give presentations.
