The video below requires some explanation.  FRONT is an interactive system motion capture system that records 3D "pen" strokes -- sending that information to a computer afterwards - apparently to be "printed".  (Video after the jump)

And what post about interface evolution would be complete without including the amazing Jeff Han?  Sure, the iPhone does multitouch, but it doesn't use tilt or pan technologies to navigate a 3D world!  On that note, why wouldn't Apple create a next gen mouse similar to the iPhone/iPod touch that would marry the multitouch experience with the built in accelerometers to deliver an intuitive 3D input interface?  This would change the face of both gaming and virtual world navigation!  And couple this technology with the Japanese mixed reality avatar-like technology featured above (fed by an integrated web-cam) for more human facial gestures, and you've got the world's BEST mixed reality home PC!  Dell's released a World of Warcraft unit, here's to hoping they pick this up next!  Any thoughts?
