The Telectroscope, a really neat art installation by Paul St. George that is operational from today through June 15. Here’s the gimmick from the website:
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 will finally be completed. Immediately afterwards, an extraordinary optical device called a Telectroscope will be installed at both ends which will miraculously allow people to see right through the Earth from London to New York and vice versa.

Wikipedia gives us a little more information:
From May-June 2008, artist Paul St George will exhibit two outdoor interactive video installations linking London and New York City in a simulated “telectroscope”. Although St George claims that the device works using a transatlantic tunnel started by his great-grandfather, it is actually the product of two high definition cameras connected through a fiberoptic link.
I’m really looking forward to visiting it when I’m in New York this weekend. Hopefully going at around 3-4 AM will allow me to skip the curious crowds and also show me the London Bridge area as our friends across the pond are waking up.
