Edge has created a custom start-up sound for the groundbreaking XO laptop, designed to help children in developing countries 'learn learning'.

One Laptop per Child, the non-profit organization behind the XO, revealed details today, as the purchase programme went live in North America.

The start-up sound accompanies a unique animation in which an "XO" spins 360 degrees to look like a child. One Laptop per Child (OLPC) manufacture and distribute laptop computers that are sufficiently inexpensive to provide children in developing countries with access to knowledge and modern forms of education.

"I'm delighted to support One Laptop Per Child," said Edge. "It's an amazing aim to use this new technology to help children all over the world."

At present the laptops are only available in North America - when you buy one, you also provide one for a child in a developing country.
