Let's face it - there are two killer devices that are going to dominate this Christmas. If you're over 25 then you're likely to be on the receiving end of a Kindle shaped package, and if you're under 25 then your stocking is likely to be packing Microsoft's Kinect.If you're one of the younger generation, then lucky you, but with everyone else getting on board the Kinect express, you'll need something to make your motion sensor system stand out from the crowd.How about this Swarovski Elements Kinect edition which features over 5,000 genuine Swarovski crystals?\n\n\nTacky? Definitely. Over the top? Without a doubt. But we bet you still want one.Costing just over \u00a3400, the blinged-up Kinect is a bit more expensive than the regular edition but think of the money you'll save not having to buy a Disco ball to make that Dance Central experience all the better.
