I could talk about this site for hours, but I'm gonna keep this short so you can just get on and enjoy it for yourself.
It's an interactive version of KLM's magazine. The experience is designed to perfection, transporting you to 50 destinations at the push of a button and making you want to leg it to the airport instantly, and they've seamlessly integrated a competition you just find yourself entering. The feedback is unexpected yet delightful, and entirely non intrusive.
It's a relatively simple build, and yet the whole is definitely more than the sum of its parts. Hats off. Try it for yourself.
