The Swiss Federal Statistical Office is Switzerland’s national center for public statistics.
One of the many bits of information that they keep track of is traffic flow –
especially the number of vehicles and their speed –
in areas such as the very well-travelled Gotthard Road Tunnel
which is the third longest road tunnel in the world at about 16 km.
This information has been transformed in real-time by Sabine Haerri & Yvonne Weber
who have transported it to a bench-like structure embedded with speakers and vibrating platform.
As the traffic increases in this Swiss tunnel over 600 km away,
so do the vibrations sent right up your back as you lie flat and happy.
The hotel in the background is quite wonderful too.
