Following the breath, virtually

I'm still waiting for my neural activator thingie from OCZ (I could really use it today --the coffee isn't working) and still thinking about novel ways of interacting with space via technology.  Here's one that I'd really like to try.  A breathing interface.  One floats through a beautiful virtual environment on movements guided by the breath.   It reminds me of a hard year I spent training in some Vipassana techniques I was trying to learn with a local Buddhist group.  There, the idea was more to use the breath as an instrument of calming though rather than as a navigational device.  However, the primal instruction was always to "follow the breath."  I wonder what kinds of interesting mental spaces we'll find as these new technologies make brain and machine connect in new ways.
