This is seriously one cool little gadget. We had the pleasure of trying out one of these recently and were absolutely impressed by it. We have seen this technology hover on the market but never really catching on as it was too niche and did not work well enough without many devices.
Essentially what the Celluon Magic Cube is, is a projection keyboard and a multi touch mouse packed into one nifty little cube. The device projects a keyboard onto any table top and using sensors to monitor your finger positions, behaves like a real keyboard, allowing you type as normal. The unit connects easily to your electronic devices via Bluetooth or USB port. It also works comfortably across Apple and Windows latest operating systems.
Expect to pay in the region of R1500 for this gadget, according to Kalahari.net (7th April 2013)
