3D movies are a gimmick to raise ticket prices (with the exception of Avatar). 3D TV is a conspiracy to get me to buy another HD flat screen to replace the one I haven’t paid for yet. I also look stupid wearing 3D glasses over my regular glasses. Or, I should say, stupider.
I’m going to wait for Holographic TV. It’s a lot closer than you think:
Oh yes, I remember Live Earth in 2007. Holographic performance by someone I can’t remember, accompanied by holographic speech by Al Gore. Live, as far as I know.
