I've seen some pretty cool Flash sites out there but I think this one has to be one of the most innovate. Web designer Andreas Lutz has created his portfolio site using Flash and utilizing your computer's webcam and microphone to let you surf his site without need for a mouse. You use your hands to make gestures that the webcam tracks and you can use speech. It's freakin' amazing!
When you go onto the site all you first have to do is some simple calibrations and then you're ready to start speaking and waving your hands to surf his site. He created a cool video to show you how it works. (See below)
And here's his site: http://www.andreaslutz.com/
