Writing on the Walls

Pioneers of “writing on the walls”) will be intrigued with the work of Hiroshi Ishii at MIT http://tangible.media.mit.edu/people/hiroshi.php
He was here last week to give a talk at Stanford and seems to have some solutions to some questions a lot of us have been wrestling over — how to merge the power of physical/visual communication with technology/telepresence.
