Placing Mountains in the Urban Environment?

So I found myself thinking about mountains as barriers and landmarks - I've already covered this previously - but I started wondering what it'd be like if I could somehow place mountains, or rather some representation of mountains, into the urban environment. How would people react? How would they use them. Would they become new landmarks, after a fashion?

I'm really into locative art / locative media, so this is what I immediately thought of as a possible way of doing this. One of locative art's applications is as a way of placing virtual objects in the context of a real environment, a kind of augmented reality, via smart phones, Wi-Fi and GPS tracking. More broadly, it can mean anything that uses location-based data and some form of context-sensitive media experience. Even more broadly, the term's been used to describe any kind of temporary or ephemeral art (i.e. light painting, projection, temporary sculpture etc.) that is tied to a specific locale. In my case, though, I'm thinking along virtual lines. Useful links below:
