This project is solving the Alert-Alert! challenge. Description
When you take a photo of an astronomical event with Ripple, everybody around you is invited to also take a photo. A thumbnail of the original image is displayed so that the user knows what they are looking for. If they can also see the event, they take their own photo and everybody around them is alerted, and so on. If they are unable to see an event from their current location, a simple shake of their device dismisses the camera and marks their location beyond the viewing area of their event.
Ripple also allows users to browse events, seeing each photo, where they were taken, and the area in which the event was visible. Ripple has the potential to collect a vast amount of useful data about rare astronomical event.
