excellent!! A whole new meaning to interactive!
I thought they would do something like that after the movies Minority Report and The Island.
In fact there's something like the Minority Report thingy in the market already, and it is in Singapore. I've seen it during a shoot recently. It's very very impressive.. There's a sensor hanging away from the screen, and you just need to hover your hand within the sensor area to 'select' photos, and if you don't want, you just 'grab' it and throw out of the screen, it will disappear.
Where can I buy this??
I assure you that even if they were willing to custom make one for you, it probably wouldn't be worth the price.
