Well, it's certainly interesting, but as far as I can tell, completely useless. However, if you've got some time to waste, definitely check out the Sundata Airbeam, a USB attachment that lets you conjure up lighted images from your cellphone or PC. With a bunch of LEDs running down the front, all you have to do is sway the Airbeam in a quick semi-circle and the LEDs will form a continuous image using the onboard accelerator sensor which adjusts them according to speed. It can store a maximum of 28 characters text and images combined and can display 8 characters at a time. Get it in pink, blue and red.
