I want to develop Windows WPF application using Kinect with great GUI/NUI. I've found really nice examples of user interfaces that could be even more admirable using Kinect device. For example: prezi effects - http://prezi.com/jipjiqvj6dsc/about-perspective/ one big wall and really nice zooming / moving. I was thinking about something similar for Metro UI too.
Do you know how to create those nice gui elements in the WPF? Or maybe you heard about good resources about this topic?
