Take one part MacBook Air, one part Microsoft Surface and some 3D "z-axis" interaction and you have the Zen PC concept. The Zen PC is being labeled a sandbox PC. The unique nature of the tablet-like PC allows for users to operate the PC without the use of eyes because everything is done with an active surface that changes texture as you operate.

The technology used in the Zen PC is far from ready, but the idea of a PC for the blind or visually impaired is one that could be very useful and helpful. The Braille applications would be endless with a shapeshifting interface like this one.
