A group of programmers have created this LED that serves as a kind of notification system.
The device is called Blink (1) and is an LED that is connected to our computer or laptop via a USB port. We can program it to notify us of the arrival of mails, notifications of new tweets and Facebook, we also know when a download is completed and it will show us the change of weather. They have designed several apps to complement the device and the user can be notified of the things they think are important.
Blink (1) cost $30 and available for Windows, Mac and Linux.
