Time for Viral Video Rewind, our weekly look at the latest, greatest viral videos on the Web.
This week, watch a snowmobiler defy gravity and a young man do a handstand on two fingers - he's said to be one of two people in the world who can pull that off. Then, how to play any instrument brilliantly in a viral video, even if you can't play it at all.
Plus: a cool app to create instant harmony, the ultimate relaxation video, amazingly talented young musicians, and a pop mashup that puts others to shame.
Links to all these videos can be found here. (Or here for a shortcut.)
