nice post on technology that predates kinect..I wonder if it might appear one day in Opensim..

“$2,000 is the current bounty for free/open Microsoft Kinect drivers (via Adafruit Industries), which really jarred some memories for me. Whatever happened to ‘Hands Free 3D‘ – the “prototypical interface” that enabled the control of virtual worlds “hands free” …without a mouse or keyboard? Competitors for the bounty might be wise to look it up.”

NB some engadget kinect hack/tools
