I looked for similar projects on internet, here is what I found :

• SNCF advert

It's clearly a mockup(not a live footage) or at least staged for the advert. But the idea of a door is quite nice.

• Sharing faces art installation

It was also temporily installed in my city, Rennes, but unfortunately I missed it.

• A well between between China and France

I've heard about this one but I couldn't find it on internet...
