A laser-projected keyboard

The aptly named MagicCube will blow you away.

If you’re over 40, you surely remember the gold ol‘ days when you pounded away on your manual typewriter, which required about 5 kilos of downward force to press every key. Here’s an overview for all you kids who grew up with flat-screen computers: Each key corresponded to a letter of the alphabet that was connected in a Rube Goldberg-esque fashion to a thin metal arm. Attached to the end of each arm was a tiny die-cast letter. Whenever a key was pressed, the arm swung, like a mini-hatchet, into the paper with a resounding “clack.”
Electric typewriters and word processors came and went, but keyboard designs didn’t progress much until Apple released its iPhone, with its groundbreaking “swipe-to-keyboard-screen” function. (As expected, rip-offs soon followed.) Unfortunately, the iPhone’s digital keys seem to work best if you happen to have thumbs as thin as Q-tips. The technology utilized by the iPhone (and it’s cousins – see “rip-offs,” above) represents a stunning leap.
Well, here’s another one that’ll get your attention: a keyboard that’s not a keyboard. 
The MagicCube is a small box-shaped device that projects a laser image of a full-sized keyboard, as well as a multi-touch mouse, onto any flat opaque surface. It’s easy to use, and its cool factor is through the stratosphere. (Typing something as dull as a 200-page legal brief can now be a giddy experience.)
Produced by Celluron, a Seoul, Korea-based maker of portable-input devices, The MagicCube wirelessly connects to any Bluetooth HID device, including iPhones, iPads and Androids. You can also use it with Windows and Mac OS devices via a USB connection. The key-detection rate is 350 characters per minute, and its rechargeable lithium-polymer battery provides 150 minutes of power at 700 milliamps per hour. And it sure beats pounding on plastic keys. celluon.com
