The Xpress-on™ Fun Shell for the Nokia 3220 phone gets you involved in the action. Exciting new motion games get you closer to the game because you're tilting and moving your phone as you play. Light effects and vibration complete your gaming experience. And when you have something to say, you won't go unnoticed. The eye-catching wave messaging flashes your message in the air. Just wave your arm and let the lights speak for you.

As you can see on the picture, the newest addition to stupid cell phone features is a mid air Text message display.
now you can project your messages in the air for everyone to read ...
now seriously ... why would anyone want to use that ?
I feel we are working our way into a world of non verbal communication... I see people sending text messages to people on the other side of the bar ... is it so hard to get up, walk over there and ask the question in person ?
are we being pampered with gadgets that have no real use ?
Besides the complete inutility of this feature ... I don't really understand how it works.
As far as i know, when you want to make a light projection visible and readable, you need some kind of surface to 'break' the light on. how can mid air be any kind of screen ?
I have heard of holographic projection, but I don't think this is done with mere leds... info on this will be appreciated.
