A bit of fun for Friday, here’s a nice little animation, as part of the Science of Sochi series on the BBC Sport website, explaining the role technological innovations play in the Winter Olympics.
There are also animations on the body’s performance at extreme conditions, and the development of ski designs for different events.
Team GB Snowboarders Jenny Jones and Aimee Fuller are into the Semi-Finals of the Slopestyle event having just missed out on qualifying for the Finals directly.
Coverage of the opening ceremony begins at 3pm.
