Using JavaScript to detect Flash Player

Have you ever been to a Flashed site that provides a prioritization of actions for all entrants by stating, "Enter this door if you have Flash Player or this other one if you don't"? Have you ever created such a site? Now you can add this kind of invisible triage to your site - sending users who already have the Flash Player plug-in directly to the Flashed content - by using JavaScript.

Methods of detection
What to look for
Substituting an image for a Flash Player movie on the fly
Sending users to one page if they have Flash Player and another if they don't
