I don't know about other browsers, but Firefox at least supports animated GIFs as favicons.

Changing favicons every time you reload the page or based on the page you are on, would theoretically be possible to do with Javascript. However I highly recommand against it. A favicon is used to quickly determine which tab contains which website. If it changes all the time it loses it's purpose.
