Prezi is a flash based presentation tool with zoom and pan ability. Very agile - take your presentation in any direction (as long as you know your content).

Free to use if you want to leave your content accessible on line.

Have a look at one of mine online. Step through the planned presentation or just click anywhere in the picture to go to content related to that area.
