Prezi is a way to jazz up your class presentations. As a visual learner, my attention is held better by something that is visually stimulating (e.g. not a white slide with black lettering). Prezi allows you to present the exact same content you would in any other presentation format, but allows for more excitement. We used this a bit during institute this summer and it was awesome. This link is just as much a resources for me, because I want to start using it more as well. I would encourage you to check it out if you do a slide show every day in class.
