One of the greatest assets of rich media is the possibility of using input devices besides the mouse. Since Flash Player 6, the plugin has been supporting the Camera and Microphone classes, allowing users to have a new set of experiences.
Even if some computers aren’t bundled with webcams or some people just hate standing in front of one, microphones aren’t so intrusive, and it’s worth considering them as a great asset when creating interactive experiences for the browser.
So why don’t you put your mouth where the fun is:
