Google Earth has launched a special teaser for Christmas Eve. You can track Santa’s fabled workshop and flight from your desktop using Google Earth.

“Every day from December 12th until Christmas Eve, a clue will appear outside Santa’s North Pole workshop which, if you can solve it, will lead you to a toy hidden in a Google Earth satellite image. And every day, the location of the previous day’s toy will be revealed(on the Google Earth website)
And be sure to open the file again on Christmas Eve to track Santa’s flight across the world.”
