My friend Chris Chromy told me about a software package called Prezi. It is basically a giant whiteboard where you put all of the information from your typical PowerPoint slides. You can also throw on drawings, videos, reports, and any other items you think you might get asked about in a meeting. It makes it amazingly easy to bounce between graphics and allows you to zoom/pan around so you can hone in right at the detail you need to talk about. So if a neighbor asks a question about there house, you can zoom right into there house.
No more scrolling back 25 slides in your presentation to answer a question. Check out a rough traffic study presentation I put together in about 30 minutes here.
