Graphics look terrible. But that's just a MVP.Just imagine working on a detailed virtual sculpture. This will be mostly used in video games and movies. Current 2D monitors have their limitations. These won't replace monitors just as E-books never replaced physical books. They are just going to add up to the experience and make the creation process much easier and efficient with much more details accessible o the creators.
It could also be great for teaching history and even engineering with virtual 3D objects with full details of the real thing. Good Hunt!
