OLPC is distributing laptops for children to communities throughout the developing world, with trial projects underway in Brazil, Uruguay, Peru, Nigeria, and Thailand. The laptops are intended to be tools for exploration and creation; as such, all materials shipped on the laptops will be free for children to use, change, and share. Software and content collections on the laptops are all freely licensed under one of the following licenses:

Once placed in the public domain, you work may be freely reproduced, distributed, transmitted, modified, or otherwise used by anyone for any purpose, commercial or non-commercial, and in any way, including by methods that have not yet been invented or conceived.

Peter St-Andre has an excellent essay, "Who's Afraid of the Public Domain?" that outlines the reasons to release your work into the public domain.

The Creative Commons Public Domain Dedication [CC-PD]

One way to release your work into the public domain is to visit the Creative Commons Public Domain Dedication Form, which will guide you through the process of placing your work under the Creative Commons "Public Domain Dedication." The form will ask you for your email, name, and title of work, and send you a confirmation email to verify your contact information. Then, it will autogenerate the license text for you along with instructions for how to include it in your work.
