The physics of invisibility cloaks

Could an invisibility cloak actually work? Prashanth and Maria from MIT explore this idea and demonstrate the cool ways that light bounces, bends and mixes. How do the wings of the Morpho Butterfly give clues about how an invisibility cloak could work? How would light need to be channelled in order for something to seem invisible?
