Every year since 2005, Google dresses up the side bar on the left side of the search ads with holiday decorations. The decorations change based on your search query. For example, Christmas vs. Chanukah vs. Kwanzaa all have a different set of decorations.
But what is new this year is the left side navigation, which now has icons for the "everything" filter that either shows a Christmas Tree, Chanukah Dreidel or a Kwanzaa Flag depending on your query.
Here are pictures of all three and do let me know if I am missing any:
(A) Christmas:
(2) Chanukah:
(3) Kwanzaa:
We did already cover the Chanukah dreidel but didn't yet cover the Christmas Tree or Kwanzaa Flag.
Here is a look at just the left hand everything icon replacement:
Standard Everything Icon: 
Christmas Everything Icon: 
Hanukkah Everything Icon: 
Kwanzaa Everything Icon: 
Did you also notice or special Chanukah theme here on the Search Engine Roundtable? Here it is:
