An IT executive, whose offices were in the slums of India, experimented by putting a computer in the office's perimeter wall. The poor and marginalized community have little to no access to the internet and computers. The experiment was a hit, and he observed how the youth took control, thought themselves to use the computer and browse the net and then showed their friends. The projects growth around the developing country quickly inspired the film SLUMDOG MILLIONAIRE.
The project is an amazing look at the effects of public interface and how social interaction takes place around a computer.

In South Africa, a project called the 'Digital Doorway' (DD) has recently launched and was inspired by the Hole in the Wall experiment in India. The DD is a more robust computer and is placed in extremely rural and isolated areas for small communities.
