The presents below the tree

>! spell NORGE (the Norwegian word for Norway), using nautical signal flags.

The tree itself

>! is a Morse Code tree:  
>! [![morse tree][1]][1]  
>!  
>! The lines spell the following (in CMYK order, like printer ink):  
>! Cyan: GOD  
>! Magenta: JUL  
>! Yellow: TIL
>! Black: DEG    

So the message is

>! "**God jul til deg**" - Norwegian for "Merry Christmas to you"!
