As far as I'm aware Melody hasn't gone into specifics regarding her setup, however the fact that no one has reproduced it points t it being developed inhouse. If I had to put money on it, I would guess that she using Unity with one or more Microsoft Kinects sensors. Plugins to do this already exist, it just a matter of slapping everything together with some basic Unity know-how.
