This might look a bit out of place here cause even though we may have the source its not under any known (GNU/GPL...) open source licenses. The author of this program has nonetheless made available the entire source code repository of this application for the general public. He has also gone all the way to discuss and explain his code in detail.
This is one killer app which I am sure anyone would love to have. After having tried Firefox and Opera how much have I missed mouse gestures in IE(Internet Explorer)! But with this useful application I have been able to enable mouse gestures and start using them all over IE. Definitely worth a try.
Yes this is a genuine Windows only app! ;) And will work only in Windows IE.
The code, executable and article are also available at the codeproject.com site.
