video of hands (fingers) doesn't seem like the hard part here though (relatively speaking, I'm sure it's plenty hard). The hard part is recognizing the input the user wants. Tracking the finger is easy. Figuring out when that finger motion is a click is the hard part.

The video on your website is significantly more impressive than the linked youtube video. That being said, I still didn't see any "clicking". Perhaps I missed it.
