Holographic sports?
Although, when we think of holography, we tend to think of projection, of something that comes from elsewhere, I wonder what happens if you view it a few steps further. If you could, for example, draw in the air. If you could make a circle in the air and say that it's green, to then lift the circle and verbally give it weight, to form it and throw it. This allows us to build a landscape. With others standing beside us, or on the other side of the world, for that matter. Or we can develop new sports and games in this environment. With real people and virtual humans and creatures. With holographic dragons, for example. Forms of experimental theatre are great too. You use your fingers to draw a door and you have a door. Of you just say what you want, and it'll be there and then you can reshape it a little with your hands. Or how about musical instruments you can play with your entire body? That track how your body movies and creates music to match? Others could dance to that. And of course the 3D rendering of your house, your car, or just a vase you can then have produced in reality. Wired World. Any other ideas?
