I thought about trying to do something specific to Halloween but frankly I procrastinated and decided to talk about only something barely related. This info will not change your life or frankly help it. However, being someone who uses Google everyday, I always like that the Google logo changes depending on the day and its significance. They do one for holidays but also any interesting events going on like the Olympics. This is a page that shows all the different logos since they started. Not much here but give it a try.
