The Future of Digital Photography

I think a small detail that was really cool was when they were talking about, you know, having that home cinema or being able to watch on an infinite screen kind of thing. The reflections from the screen and the way the light behaved interact with your environment. So if you have like a TV, like imagine a virtual screen in front of you, it's wearing glasses, imagine we're wearing glasses. And basically it's something very blue was on the screen. Like there'll be a blue slight hue that's all over the room in a way. It's just those little touches that make it seem like you're really there. I don't know why hasn't anyone done this before?
