Wow the theory seems simple enough.. An 'Eureka' moment when you realise how simple it is... The technology behind it though, should be mind-boggling haha... With 3D photography coming up to a store near you, I think the advent of 4D videography should be up next. We've already got 4D ultrasound scanners so 4D videography shouldn't be that much far off.. We can probably incorporate that technology into CT scanners and the like too... Provided the patient doesn't die of X-rays first...
Anyways, the little pimple on your face can now be viewed in 3D!!! How cool is that?!
