A colleague of mine recently delivered a presentation using http://prezi.com/. Probably. like you I’ve sat through and delivered many presentations using Powerpoint and I’m probably suffering from ‘PPT fatigue’. It was interesting to see this tool used, It uses Flash, so there are accessibility issues with using it, however it gives you a novel way of presenting and also thinking about how you are going to present. Some examples of presentations from the Prezi website can be seen here:
