If done well, 3-D films can be quite impressive, often cleverly simulating the idea of things coming out of the screen so that we feel like we're able to touch them, though it's only in fact our eyes which are ever being assaulted by the effects. Typical effects include pleasant or nasty smells, smoke, vibration, tickling and water spray

Alternatively, you might have splashed out on the latest technology and invested in a 3-D TV, for which you'll still need to wear those daft specs, but at least you can do so in the privacy of your own home!

During the festive holiday season at the end of 2011, there's a chance that you might have taken a trip to the cinema and donned a pair of those silly plastic glasses in order to enjoy a 3-D movie experience.
