Science Fiction? Nope, it's possible and it's real, and you can buy one. The M2-series Heliodisplay's from IO2Technology can project any image, live video or VGA input in mid-air with a 30-inch diagonal (76cm) display size - just like that floating in air!  Cool eh? 

The Heliodisplay's projected image hovers inches (up to 28 inches) above the unit, so it can be easily hidden in furniture or behind something.  But, what makes the M2 Heliodisplay more interesting is the cursor control feature; the M2i series allows a finger placed on this floating image  to act as a mouse - just use your finger to move windows around, click or even drag in mid-air.

The M2 and M2i Heliodisplay's can use PC, Mac, NTSC, PAL, SECAM,  DVD and HDTV inputs and weigh about 21.8 kgs, so they are portable enough to be carried around. The M2  Heliodisplay is available now, but pricing information is not public yet. We love it;  Now, who do we have to sell for getting our hands on one? :)
