One Computer A Month (OCAM) is an initiative started by Brandon Perry in order to spread the word of Ubuntu one computer at a time. They donate to schools and homes in need of a computer for basic usage (word processing, email, and internet browsing, etc...). As the name implies, at least one computer a month is donated.
