Swisscom found a way to combine online and street media: by writing tweets in snow. The company helped to cheer on the Swiss competitors of the Alpine World Ski Championships in St. Moritz. It took two days to carve a one-line design of the tweets and portraits of the ski-champions into a giant snow field, a canvas of 16 football fields. Specially engineered snow robots were used to carve the design, which contained 20 km of messages.
