Flowboard

Flowboard is a vertically integrated iPad presentation tool which allows users to create presentations based on "screens" and incorporate interactivity. Screens are created using basic touch gestures, and completed Flowboards can be shared via URL to iPads and on the web. Flowboard allows for more interactivity than a traditional Powerpoint-esque presentation, and is designed for more individualized used than, for example, Prezi. The downside, of course, is that use is somewhat limited to iPad users.
