Prezi

 Virtual Presentation Software.

Prezi is a web-based presentation development platform (called prezis for short). It's similar to other presenting applications like Microsoft PowerPoint, but it has some special aspects that make it a strong substitute. 

It has been popular in businesses and schools in recent years. If you're trying to create a presentation that's a little more eye-catching and entertaining, Prezi may be for you.

Many styles of presentation software use a slide-based technique, where you switch back and forth between individual slides, just like pages of books. Nevertheless, Prezi uses a canvas-based approach. Instead of just using slides, Prezi has a very big canvas that pushes the presentation around, zooming in and out to see multiple frames.
