I normally warn readers about long videos but all you'll get on this one is encouragement. Watch the video! First, from the video's description:
Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look "around" corners or see inside the body without X-rays.
You can read and see more about Dr. Raskar's work at MIT's Media Lab here.
