We’ve been promised proper 3D video since I was old enough to watch bad shark movies at friends’ houses. But the wait may be nearly over – several companies, including Philips, are building new displays that produce the illusion of three dimensional objects without the need for any daft two-coloured eyewear. The tech is only for malls and kiosks at the moment, but Philips reckon they’ll be rolling out 3D TVs in a couple of years – which is going to make all those who’ve recently shelled out for high-def flatscreens more than a little gutted.
