This is a hairdryer? Well, a concept for one at least. The peculiar shape is the result of watching hair stylists struggle with traditionally shaped dryeres. With the L-shape, the goal is to allow a more neutral grip while still providing the same flow of air.
My short hair doesn't require a hair dryer, but watching my wife contort her arm into all sorts of awkward positions while blow drying her hair makes this design particularly interesting. Hopefully the concept makes it to market.
