“Hardly anyone knows that a secret tunnel runs deep beneath the Atlantic Ocean. In May 2008, more than a century after it was begun, the tunnel has finally been completed. An extraordinary optical device called a Telectroscope has been installed at both ends which miraculously allows people to see right through the Earth from London to New York and vice versa.”

This is the description of the Telectroscope from the artists website, it could also be that it is all done by fiber optics, the first explanation by artist Paul St George is a little more magical though.

One end of the “tunnel” is next to Tower Bridge on the Thames river in London. The opposite end is next to Brooklyn Bridge by New York’s East River.

It is similar to a gigantic webcam, people on one side can look in and see people on the other side. Unlike using a webcam however most of the people on the other end will be wearing clothes.

You can view a video of the piece over at the BBC.
