Know this “Telectroscope” thing that’s been all over the internet? The transatlantic “tunnel” that lets people in London and New York see each other by looking through it? And somehow there’s enough light and proper optics for the image to stay intact and visible? And the artist somehow constructed a transatlantic tunnel on an artist’s budget?
My technical curiosity about its feasibility got the best of me.
