Danish programmer David Heinemeir Hanson is a person you may not have heard of, but I guarantee he has impacted your life. This gentleman created a web application framework called Ruby on Rails. It powers some of the largest sites in the world like Hulu, Funny or Die, and the even the earlier versions of Twitter where RoR creations. Thanks to this, David has quite a stockpile of cash, and he uses that money to indulge in his lust for petrol. David likes to contact some of his favorite automakers to request custom one-off “HH” models of cars for his collection. His latest delivery is a custom Koenigsegg Agera HH, and it looks stunning it is metallic blue paint.
