Topotek1 landscape architecture office from Berlin presented a unique installation for the Xi’an International Horticultural Exposition in 2011 – a hole to another side of the world.
As visitors stand close to the edge of the installation, they can actually hear distant echoes of the sounds from the other side of the globe: some sounds come from New York City street life, some from the docks of Stockholm or even from the pampas of Argentina.
