Kinect + dancing lines

Hi there, I'm trying to do a very well known interaction in QC. I want to use the kinect and a simple grid that moves or deforms following the movements of my hands/body. I did it using eMotion but as you know emotion is no very stable and I fell more confident using QC. The main problems is that I do not know what kind of surface/mesh or solid do I have to use and how can I link the X,Y and Z coordinates I got from the kinect to that surface/ mesh.

the first 25 seconds of this video can be very usefull to know what I'm trying to do... just simple horizontal lines that moves/deforms when the hand pass through...thank you for you help
