How can I make my streaming presentations more dynamic?

Using a technology called SMIL (Synchronized Multimedia Integration Language, a W3C standard for Web media) you can combine different media types-audio, video, text, still images, Flash, etc.-in the order you want them to appear, and place them where you want them to appear in your player. It's one thing to simply show a video on the Web, but much cooler when you can create a fully interactive presentation featuring multiple media types.
