Listening to the Earth
A bike rack that I used on my daily commute vanished, leaving a hole in the ground. This is an action I did in response to this disappearance.
I installed a can telephone into the hole where my bike rack used to be. I used this obsolete technology to listen to the earth. I left the telephone for others to experience.
The can telephone was removed 4 days after it was installed in Newton, MA USA.
