Flash Technology
What you are looking at, (and possibly listening, too!) is a flash movie.
Macromedia Flash is the key to designing and delivering low-bandwidth animations, presentations, and Web sites. It offers scripting capabilities and server-side connectivity for creating engaging applications, Web interfaces, and training courses. Once you've created your content, 97.6% of the online audience will be able to view it.This is only the beginning
You will be amazed at the breadth of possibilities that a flash site will open for you. Perhaps you want some sound and a small animation, like we have here. Or, you may want a flash theme and then a flash menu reproduced throughout your site, as was done for John Mcdaniel. Or for a fully interactive site, check out Jackson Browne's site. It takes awhile to download, and a site like this is not for the price conscious, but wow! What an experience!
