Prezi is a neat way to present information. Very intuitive and sharable too! On our main page there is one example of many I've made and used in my workshops.
I enjoy creating Prezis for several reasons:
1. To present photos that go along with a talk
2. To embed youtube videos if using in presentations (unlike ppt, no technical difficulties)
3. To engage the audience with zoom in and out - highlighting and resizing information.
Here's a great list of ways to use Prezis. They aren't difficult to make - also offering a great selection of tutorials to help. My recommendation (and this goes with power point also, is to simply "borrow" a presentation and use that as your template. Go through the Prezi reuse library,, find one whose design you like and then click the "make a copy" button at the bottom right.
Try making a Prezi and you'll see the power and possibility. A great option and also a great place to find already made presentations...
