Kliment, who is involved in the reprap project, has just made a great holiday/christmas prusa mendel version. This might be the excuse you need to start building a RepRap, at least I´m jumping on and starting my build! You will find a new STL file every day, Christmas-themed in one way or another! And on the 24:th you will have all the parts so you can stay up all night building.
Christmas doesn't get better than this...
