Turn your table into a virtual keyboard with the awesome Celluon Magic Cube. Using motion detection technology, this laser-projected keyboard will be the most useful thing you’ll ever buy. Pocket-sized and easy to install (USB-connected or Bluetooth; no drivers needed), the Magic Cube can run for up to two hours of continuous typing when wireless. Charges through the USB.
The Magic Cube detects movement just above the surface of each projected key, so typing is a bit different from your everyday usual keyboard. Some practice will be required, but you’ll get the hang of it pretty soon, don’t worry. It’s compatible with almost any gadget out there (except for Kindles).
