One Million Giraffes Project
Norwegian web developer Ola Helland made a bet with his friend Jørgen on the 6th of June (2009) that he could get a million giraffe pictures by the end of 2010. 440 days later he proved his friend wrong with help of people from all around the world. 102 countries helped out showing Jørgen how amazing the internet is. You can find more than one million giraffes on his site here.
