Most Android phones have a front-facing notification light to let you know that you’ve received a message or push notification of some kind. While the iPhone also has notifications, it only does so with the rear-facing LED flash. If you have your iPhone face-up on a desk, you may never notice that light. With FLASHr, you will.
What Trey DeArk and Terence Green have done here is create a case for the iPhone 4 and iPhone 4S that effectively reflects the light from the LED flash so that it envelopes the outside of the phone. In effect, your iPhone lights up to let you know that you’ve got a new text message or Facebook update to read. Because the light is reflected in multiple directions around the phone, you’ll see the notification regardless of orientation.
But what if you actually want to use that LED flash to take a picture? There is a small cover that allows the LED light to reflect back into the case for the notifications, but you can slide that cover open to reveal the LED light again. This way, you can take photos as you normally would. Check out the Kickstarter page for more information. They plan on doing multiple colors and the early bird special gives you a free custom combo case with a minimum pledge of $30.[Source]
