Prezi makes some very dynamic online presentations that go beyond slide shows and videos, as they add an interactive component to the experience. I found Prezi very easy to use and it has a simple help site with examples. Very cool.
The other wonderful thing is that you can sign up for the "enjoy" version, which has more features than the free version, as an educator or student for free. When you sign up for an account, notice the Student / Teacher Licenses in the orange/yellow box on the bottom left.

Use the "Learn" tab... simple videos on how to use Prezi: http://prezi.com/learn/
Use the Manual button on the right of the Learn page (http://prezi.com/learn/manual/) for very easy to use help pages and examples.
