The One Laptop Per Child brings learning, information and communication to children in developing countries. When closed, the entire unit is sealed, protecting it from dust and dirt; when opened, it has a whimsical and tactile richness. The Wi-Fi antennas, also called Rabbit Ears, give the OLPC a character-like personality. Everything on the laptop serves at least two purposes for a sense of economy and efficiency: Antennas double as a cover for the laptop’s USB ports; the surrounding coloured bumper is also a seal to keep out dust; the screen is a colour image screen and a high-contrast black and white screen for reading text in bright sunlight.
