Flutter: Change songs, Power Point Slides with hand gestures via webcam

From last month I have started developing a Windows 8 App. As I am working on Silverlight from the very first version of it, I am very familiar with XAML and which is also the base of Windows 8 App development (If you go for C# and XAML combo.). I am working on some BI which is not part of this topic and I will discuss about it some fine day. The point is when I installed it in a Windows Surface I was amazed. The Look and Feel was a great experience. Life always wants more. Me too. I thought what can I give more in this App depending upon the Surface features.

Some day back while I watching TV; I saw an advertise of Samsung Smart TV where a person can change channel with just a hand gesture. I thought can I implement this in my Win8 App? Asking Google I found a very good freeware: Flutter. By installing this software you can change a song playing in Winamp or WMP. Also you can change the slide of a PPT while you are demoing people. It needs a webcam. When this app runs, the webcam will get on. Your hand should be within 6ft of it. Fine ... Fantastic. ... But is that what I looked for? Nope. So start to find more about it. 

Now I got an open source project of a hand recognition system writing in C#. Here is the link. I am still working on this. Will let you know when I finish this. 

Technology is Fun.
