Slopestyle snowboarding will make it's first appearance in winter Olympic competition this year. It'll be a thrill to see some of the world's top competitors going at it in one of the most entertaining forms of the sport.
Without a doubt, whoever takes home gold (and probably silver and bronze) will have to land a stunning and relatively new maneuver known as the 1440 Triple Cork.
It can be tough to follow, but basically the move consists of four complete rotations (4 x 360 degrees = 1440 degrees) and three instances where Billy appears to be roughly upside down (i.e. inverted in snowboarding lingo).
The maneuver looks complicated, and is certainly one of the most difficult moves in the sport. You have to wonder how anyone could manage to put all the pieces together to land it consistently in competition. Fortunately, snowboarders have physics on their side, which makes this trick (a tiny bit) easier than it looks.
In order to get a handle on what's happening during the 1440 Triple Cork, first consider my snowboarder sketch.
