See Through Dual Touch Display
Take the idea of the iPhone-style touch navigation and then times that by two.
This totally cool dual-sided transparent touch display from Teraokaseiko is definitely on the right track.
Perhaps someday it will develop beyond wicked games of, Naughts and Crosses, Battleship and Connect 4.
At the moment it’s just a monochrome 256 x 120 EL-panel prototype for now, but it recognises those multitouch gestures like pinching so there’s plenty of promise in the idea.
