The Zero Angle is a concept that flips a camera lid 360 degrees. When flipped around, the protective cover acts as a fully functional screen. It’s one of those easy-to-implement, we-should-have-this-already concepts, which hopefully means we’ll be seeing real products like it soon enough. As long as you put the power button on the face or make it non-functional when it’s closed it’s not so great is that it’s just a concept for now.”]
