Shockwave is a method of viewing interactive movies on your website. You can make innumerable things with them, from moving buttonbars to animated logos to complete interactive experiences. If you are viewing the multimedia version of this site, you've already seen several examples of Shockwave, including the opening WebSpan spin-in, the buttonbar at the top of the page, and the "Click Here for Shockwave" button that directed you here. If you are not seeing these movies, you can download the necessary plugins from Macromedia, Inc.'s site. While you are there, check out the Shockzone to see further examples of Shockwave on the Web.
