One new technology that is useful in specific presentations is that of Prezi. Prezi is free to use, but buying the license has some advantages, including making your presentations private. This is a presentation I put together after only being at GWAVA for 2 months. I had to give it over and over in our booth at BrainShare 2011. People had to watch my presentation before we would give them a T-shirt. They loved me….well they really wanted a GWAVA T-shirt.
