Some organizations are very serious about their logos. They produce exhaustive guidelines on how their logo should and should not be used.

The Drupal community takes the opposite approach. The Drupal logo is called "Druplicon" and is released under the GPL license. That licensing allows designers to do whatever they want with the logo.

That design freedom has led to some funny, imaginative and downright strange variations on the Drupal logo.

Here are 27 of our favorites from events around the world.
