Bitcoin and Opencoin are "sons" of David Chaum's Digicash both. Chaum is one of the most important cryptographers and freedom fighters in the world and invented in the eighties the first digital cash, that was refused, attacked and destroyed by credit card companies societies, that instead wanted to propagate a model not based on anonimity. The big difference between them is that Bitcoin is a complete currency system instead Opencoin is the system to make a currency (a digital mint). Bitcoin you need to use as-it-is, with Opencoin instead you can create your own currency system.
