Track Santa on Google Maps and Earth as he delivers gifts around the world
Basically, once Santa gets on the move -- around 2am EST on December 24 -- you can follow his movements, either in 2D or 3D, on your computer or your phone, and with Google Maps or Google Earth; just search for 'santa'. For the truly festive, there's even a NORAD Twitter account, which will presumably tweet Santa's current location in real time!
After the break, there's a video of what the experience looked like last year. I imagine it will look much the same this year, unless Santa has updated his GPS navigation hardware. Also, who knew that Rudolf's nose was quite so radiant?
