I believe first spotted by Sam Michelson, Google has a special Chanukah Dreidel and set of Jewish stars when you search for [chanukah] variations on Google.
Google has always shown decorations on AdWords for holiday searches. This year, for [chanukah] they are showing Jewish stars.
The big deal is that the "Everything" icon on the left bar on Google's search results is now a Hanukkah Dreidel instead of the standard icon, which is awesome. It is sad not to see a special doodle on Google Israel on such a fun holiday, but I believe this makes up for it.
