Jeff Gburek _ diaphragmatics: prepared speaker, preparations and keyboard

This will have to do for now. It remains more of a demonstration than an a finished work of any kind because I could not figure out a way to mount the camera above so I could use both hands to manipulate the preparations. Adding to the awkwardness is having to keep the action in the frame, the parallax between the image on the monitor versus the eyes view of the actual objects. But this begins the discussion. There are many other things one can do with both hands and also many preparations I use that require both hands just didn't get into the mix.
