I just enjoyed looking through previous Google Doodles.
I'm sure you've noticed that Yahoo! and Google change their logos for special events. Well, this week, I noticed that the Google logo was progressing. My hubby then realized that if you click on the current logo it shows you the progression of the logo changes. Back to me. After he pointed that out, I noticed the URL had a file name with a number. I started changing the number (going backwards) and found a whole pile of prior Google Doodle Logos. It was fun to look through them (they are mostly Winter or Olympic in nature, but I found one from July too).
