Now this is a very interesting sight, this developed from an idea in the Industrial age around the 1800s. Where they wanted to make an undersea telescope of some sort from London to New York. And now in this modern age, an artist took this interpretation and made it true with modern technology, but instead of a tunnel, it is connected through fiber optic cabling with a screen to see the other side, it is real time and you can see people walking by or looking into it. The piece itself is a work of art and the technical idea is very fun.
