Telectroscope

Earlier this week, I went to City Hall to look at/through the telectroscope, an art installation which is on the riverbank until Sunday. The story is:

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.

Okay, something tells me this might not really be done by a long, long tunnel and some mirrors. Nonetheless, you truly can see New Yorkers at the other end (by Brooklyn Bridge) in real time - there were some very excited people waving at friends when I was there - and it's a fun idea. See it in lots more detail on the website.
