Oh Motorola, you sly, sly devil. How could you hide this future-thinking patent from us for so long? Seems the company has decided our cellphones just don't have that jazz, so it has created a patent to make your phone "dance." Using what they call an "ambulatory" device, which sits on four vibrating feet that shake at different speeds and in different directions, your phone will jiggle around like J-Lo when it rings.
The device could, for example, shimmy in a clockwise direction to signal an incoming call from the office, or wobble counter-clockwise to alert the user to a new message.
And that, folks, is that.
