Many in the Xojo community do not know this, but I personally am involved in the NORAD Tracks Santa program (since 2006). Each December 1 and remaining during the month, the NORAD Tracks Santa website is live.
Starting Christmas Eve, you can track the flight of Santa either in 2D or 3D as he flies around the world, delivering presents. Tracking Santa is a fun activity to do with your kids.
The website includes Christmas music, a lot of background on the program and FAQ about Santa, plus free mobile Android and iOS games released "advent style’ during the month.
