Flash Detection (dithered.com)
When separate Flash and HTML version of a site would be too much work to develop and maintain, an HTML site with optional Flash elements is preferable. This script would then be needed on any pages with optional Flash elements.

Alternatively, you could use it on a splash page and change the url of any links based on the Flash version.

The script can also detect if no Flash is installed or if a detection is not possible (for instance, on IE4.5 Mac).
