The Alpine Speech Fasting was a week-long escapade and design experiment at 2020m altitude, in a mountain above the village of Tschlin, Switzerland. It was a part educational experiment and part experiential art.

For the whole week, spoken and written communication was perceived as unnatural during daylight. The participants avoided words from sunrise to the nine o'clock evening bell’s call from the church in the valley below.

Each of the five participants was asked to bring four tools: one for communication, a second for making, a third for socializing and a fourth for rituals. The tools then inspired the daily activities, during which the participants explored and signified their shared context.

The spontaneous program explored and tested collaborative creation, educational workshop formats and experimental design strategies without and beyond the use of spoken words. 

Coming down the mountain again, a public bath in one of the village's fountain was the ritualistic closing end.
