Words Like a Neon Light, With the Wave of a Phone

BBC News reports:

Nokia is making a mobile that lets you write short text messages in mid-air... A motion sensor in the phone makes the lights blink in a sequence that spells out letters when the handset is waved in the air...A trick of human vision turns the sequence of letters into a message that hangs in the air.... could be used by friends to talk to each other across crowded rooms or open-air concerts.... could be used to play games overlaid on city streets, as a heckling device or a novel way to interact with other devices.

New ways to communicate are always interesting, no matter how trivial they may appear to the imagination. For the pervasiveness of communication, the complexity of our lives, and the way the two are intercombined, always outstrips anything we can simply imagine.
