I like the kinect mouse sample which allows control of the computer/system mouse using kinect and iam making a multiuser version of kinect mouse at http://kinectmultipoint.codeplex.com
Anyone wanting to help my project i plan on getting it to work with these programs with kinect by the end of project:
1. microsoft mouse mischief
2. microsoft multipoint mouse sdk (not multipoint server which is completely different)
3. study island (going to talk to support once i get my project in an alpha stage and might need to emulate a clicker device instead this time).
This is for a real life replacement scenario of smartboards at my work which is a K-12 organization which are 1,500 - 2000 dollars a piece.
