so i saw this on discovery channel , a man invented that.he made sth that produces thin air , low density air, then made the air to flow like a curtain then used a regular projector to play a movie on the thin air curtain and it worked the image was watchable , not perfect but it is sth.

is there anybody who have any idea how to produce thin air ?
if so , give me some ideas .and i will do some research

It wasnt thin air, I saw the same thing, it was very small water droplets that were falling, almost like a fog but still heavy enough to fall to make it a straight edge instead of spreading out. If you can find a way to make almost microscopic water droplets fall then PLEASE tell me how as I would love to have one of these in my house. In the future can you imagine the videoconferencing possibilities of these things.

yeh right , i remember now .it was on beyond tomorrow.
maybe with some searching i can reach for sth.if i can contact the guy who made this it would be wonderful .i don't think it would be an easy task but i might give it a try .u can help me if u want.
