Google also developed a Santa Tracker app for Android and a Chrome extension. "Before Santa takes off on Christmas Eve, his elves have cooked up a countdown timer to keep precise track of his departure. You can play around with his blimp, elf bus, and write messages on a frosty browser window. Once he takes off, follow him around the world as he delivers presents," informs Google.
Google's Santa Tracker has a lot of cool games and a feature that lets you send a call to friends from Santa.
