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.

Nice to see art installations breaking boundaries and bringing people together.
