prezi

Prezi (http://prezi.com) 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 users 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.

this is an example of a prezi presentation:
