When writing The Digital Sea, invisibility was one of the cool effects I thought was possible with ubiquitous augmented reality.  I didn’t expect to see tangible examples so soon.  Granted, without AR glasses, all the effects are static on the screen and only eye candy.  But what glorious eye candy Fukatsu-san makes.  The predator alien would be proud.
The second video from yummyfuture shows us how to make ghost images of furniture (or whatever you’d like to do.)
I think I could watch new Kinect video’s all day.
