Prezi is a web-based presentation application and storytelling tool that uses a single canvas instead of traditional slides. Text, images, videos and other presentation objects are placed on the infinite canvas and grouped together in frames. The canvas allows users to create non-linear presentations, where they can zoom in and out of a visual map. A path through different objects and frames can be defined, representing the order of the information to be presented. The presentation can be developed in a browser window, then downloaded so that an internet connection is not needed when showing the presentation. (from wikipedia)
In response to a growing demand, Prezi developed an educational license pack. Students and teachers can now create private prezis for free. They can have Prezi Desktop at a special price. Upon verification of student/teacher identity, Prezi EDUEnjoy is free and Prezi EDUPro comes with a special educational discount.
Using Grouping & Layering
The best prezis use grouping and layering to reduce panning that causes motion sickness, and to avoid overwhelming the audience with too many details at once. Check out this short video on grouping with frames and layering to get the most out of your prezi!
