I have a Google toolbar, so I rarely visit the Google homepage directly. I always regret missing out on Google's awesome logos! No more, I've found the index, you can see every Google logo that has ever been used (I think).
Where do these logos come from? Can the average joe submit designs? I know Google has a staff member in charge of making logos, but surely he needs a break sometimes! Now I want to work on my very own Google logo. The trick will be making something that has never been made before. Off to the archives!
Weird trivia: I just finished looking at every Google logo ever. Slow day at work. Want to know something strange? The very first custom Google logo was not for a holiday or well-known event, but appears to have been for the Burning Man festival!
