According to an AP report in the SMH yesterday, Philips have also been showing off their 3D TVs, except these models don't actually require any sort of eyewear. The TV works a bit like a "holographic greeting card, [combining]slightly different angles of the same image to create video that appears to have different depths as your eyes scan it."
From the report, it's still a bit touch and go - sometimes it's extremely vivid, other times it's just murky. But Philips believe that we'll have 3D TVs in our homes within a few years. Or at least those of us that can afford it.
The report also mentions some of Philips' other innovations, in particluar their use of lighting based products. In particular they have a water purification system which uses UV light to get rid of bacteria, which is quicker and cheaper than boiling the water.
