According the the Microsoft Research Blog, this is only one of the upcoming 3D projects coming out of Redmond. Writes researcher Steve Clayton:
I would not attempt to describe what it does in great detail, except to say that with Holodesk you can manipulate 3-D, virtual images with your hands. Whilst this is only a research project at this stage, I can envisage future applications in areas such as board gaming, rapid prototype design or perhaps even telepresence, where users would share a single 3D scene viewed from different perspectives. I know it sounds very Star Trek but this is not science fiction.
Very Star Trek indeed.
