Sony HD 3D LED Display System

The annual Japanese gadget fest Ceatec kicked off outside Tokyo this week, with plenty of cutting-edge products--and futuristic prototypes--to tempt gadget lovers.

Here, Sony's HD 3D LED Display System serves as the centerpiece of its booth. At 1,136 square feet, it's not meant to be something you bring home for the kids. But as a backdrop at a concert? Or for large-scale outdoor events, like football games? That's exactly what Sony has in mind, though it's not for sale yet.
