As a gesture of thanks, Apple is giving away 12 MacBook Pros to Open Source developers.

The new notebooks are being given to twelve independent developers who helped the company build the Open Source WebKit software that is used in Safari.

The company began the project in June 2005. "Those of us at Apple are grateful for all the work done and how it will help with future releases of Safari and WebKit," a note on the Surfin' Safari blog says.

The gift of appreciation was announced on Surfin' Safari, a blog for WebKit developers that's maintained by Apple engineer, David Hyatt.

The site notes a series of improvements made as a result of the help of volunteers who worked on the project, and promises a free Mac to each of the top twelve contributors. Five developers have also been invited to attend Apple's Worldwide Developer's Conference this year, at Apple's expense.
