Berlin-based landscape architecture firm Topotek1 presented a whimsical installation, The Big Dig, for the 2011 Xi’an International Horticultural Exposition. The installation is an enormous hole in the ground that was ‘dug’. From its edge, you can hear sounds from Sweden, Argentina, the United States and Germany.
“Cows from the pampas of Argentina, commuters rushing among transit through New York City, the maritime life of Stockholm, and layers of history so audible among the streets of Berlin” can be heard from the simulated audio connection of The Big Dig. The sounds tap into the imaginations of viewers and make them feel as if they could travel to another place in the world, other than China, through that hole
