This is probably one of the coolest pieces of video game marketing I've seen in while. Dear God it felt gross to type that. Shudder.
It's a website called Destiny Planet View and it's sort of like Google Maps for the world of Destiny. It's something of a guided tour -- there is literally a voiceover guiding you -- and you can click throughout the universe of destiny, before heading to some super interesting Google-maps style 3D pictures of the game's environments.
It's all super impressive. My favourite part was this: the website actually launches you from your current location and shoots you into space, before allowing you to travel to the different planets available in the game. That was cool. Very cool.
I won't spoil any more for you, I'll just encourage you to explore the website for yourself.
