The HAARP antenna array is being used to create a global work of transmission art
IEEE Spectrum
High above our heads, the ionosphere haloes the world with a haze of charged particles. The ionosphere was once critical to global telecommunications, because shortwave radio signals reflect off it, and so they can bounce all around the planet. Fiber-optic and satellite communications have largely displaced shortwave radio. But the ionosphere still offers unique opportunities, such as the ability to create truly global pieces of art. That’s what broadcast artist Amanda Dawn Christie is doing this Sunday evening/Monday morning. She’s using an enormous array of radio antennas—and you could be an essential part of her artwork.
