Christmas fun with Mathematica [closed]

In a previous post we saw how we can create animated snowfall. So, I was wandering what else, related to Christmas, we can do with Mathematica? Perhaps, drawing a tree full of ornaments and lights...

All ideas are welcome! I suppose it would be nice to have a post full of nice codes related to Christmas.
