This is an interesting little gadget called the blink USB. This is a little USB dongle has a RGB LED in the end that can glow different colors. The small light slips into a USB port and has lots of programmable functionality that can be used as a status light just about anything you can think of. The device will work with Windows, Mac, or Linux operating systems allowing it to work with just about any computer you might have in the home or office.
The LED inside the little flash drive can be adjusted for brightness, pattern, and color. That means you can set one color or flashing pattern to warn you of Twitter posts with specific keywords and another pattern and color to warn you if there's a problem with a server. This little thing sounds very flexible and interesting people who manage a lot of computers.
The downside is the network administrator at your office could plug one into your computer and make it easier to see if you're doing something you're not supposed to be doing in your cubicle. The device is on Kickstarter right now seeking funding with 32 days ago. So far, the product has racked up $20,779 out of goal of $29,000. You'll need to pledge $30 or more to get a blink USB LED.
