The innovative idea for the "One Laptop Per Child" (OLPC) program was founded by Nicholas Negroponte, as a means of giving children in developing countries an educational opportunity that they would otherwise never have. For a limited time, the public can donate to this worthy cause through a "give one, get one" program, giving one laptop to a child in a developing country, while receiving one laptop for themselves.
For more information, visit the OLPC official website at http://www.laptop.org/.
