Blind light

This app converts light level to vibration ,the brighter the light the more it can be felt.The idea is to use the light level so thata Blind person could make out bright areas in a room, and use to find doorways ect.So he/she would use the phone to scan the room,download sensorviewer first to test your phone has a light sensor.Press meun button to adjust the Sensitivity100% will give a strong vibration in Dimlight.50% seems best for indoors.Feedback would be great.
