Wired has a neat little article/slideshow depicting the process of designing the Google logo. It’s interesting to see the first design compared to the last (current) design, and how similar they are.
Along with this article, take a look at Google’s archive of past logos for holidays and other events. It might be worth a look into the different holidays and events that are portrayed by Google’s logo.
Also, on a sad note, a bit of technology fades into history. The Polaroid instant photos have been discontinued (over the course of the past two years). The thrill of an instant photo was one of my child hood memories. Something my children won’t have. Now we we’d have to truck along a printer to get the same instantaneousness.
