Projected Augmented Reality,Projected Augmented Reality with Unity

Hi, I want to do a projected augmented reality project. An image projected onto a table top, that interacts with objects on the table. Video projector above the table, with a kinect or other sensing.

I've used Unity a little bit in the past. Is there a tutorial, or set of plug-ins that I can use to get started with?

Thanks, John Fielden
