I saw on TV the use of a digital camera in medicine: dealing with children. By taking a quick photo of the ear of a child in pain, the nurse was able to share the image off the cameras screen with a doctor.
The cleverness comes in leaving the child alone, without being examined while in pain, for the maximum amount of time. The picture is capable of being magnified and shows a steady image instead of a struggling child! Less painful for all concerned. Clever use of digital technology.
