This may not be the most useful product in the world, but as toys go, it doesn’t get much cooler than this. The Airbeam from Korean company Sundata looks like a USB drive, but it isn’t. It’s designed to connect to some SK Telecom phones.
There are a series of pink, blue or red LED lights down the front of the device. When you move the Airbeam quickly back and forth in a semi-circle, the lights blur together to form a message or a symbol. It’s like this – hold your hand in front of your face and move it back and forth quickly. It looks like your hand is in more than one place at once. The Airbeam uses the same idea, but makes it much more fun.
You can either use the phone to enter your text or you can pay to download images. You can display 8 characters of images at a time and store up to 28 characters.
You don’t even have to worry about moving the Airbeam back and forth at just the right speed, because an onboard accelerator sensor adapts the display to the speed you are moving.
No word yet on whether this will make it to the U.S., but I sure hope so. I love wasting time and few things do that as well as the Airbeam could.
