Add a multimedia component to your web page, using Macromedia Director. You can assume that the person looking at your web page has Shockwave, but you shouldn't assume that they have unusual plug-ins.
If the file associated with your multimedia item is bigger than about 25K bytes (which is likely), then it would be best if the best if the file is not called directly from your home page, but is rather associated with a page linked to your home page, such as in:
<A HREF="mymovie.html">Click here to view my move.</A>
BUT -- Make certain your movie is easy to find!
You may want to review online documentation, such as the Multimedia Director Animation Tutorial, or newsgroups as listed at Macromedia's site, and you will certainly want to review the information about converting a movie to a DCR file (using Afterburner) and how to embed the DCR file into a web page, as described here. Don't forget that when you create your movie, you should limit the size of the stage, using, for example, "Quicktime 320 by 240" or smaller (look under the "Modify" menu, "Properties..." in Director 5.0).
In any case, your Director file should be original, created by you, and fun. It does not have to be complicated: Some things to consider might be a bouncing ball, color effects, transition effects. It should also contain at least one sound, but be careful because sounds rapidly increase your file size (and, hence, the download time).
Your web page is a way of "marketing" yourself, and multimedia helps the package sell!
