One Laptop per Child (OLPC) is a non-profit humanitarian organization whose purpose is to provide educational opportunities to the world’s poorest children through ownership of a connected, rugged, low-cost laptop. The “Give One. Get One.” campaign is a fund raising effort directed at consumers in North America and Europe. To reinforce the educational roots of OLPC, we boiled their mission down to simple, mathematical equation: children + laptops = change the world. The microsite was sent to laptop buyers, and acted like a digital hall of fame.  It invited people to add their own equation that might help change the world. To Navigate: Roll your mouse over the long equation, and then click to see individual entries and images from OLPC deployments. Then click the blue arrow in the corner to create and add your own equation. You can add or subtract individual words by rolling your mouse over the addition sign.
