Walking on Basel

Walking on Basel

Over three days of the Viper Basel 2004 festival there was an open invitation for the public to contribute to a series of walks that spelt out the name of the city. Over several session a day, the participants set off with GPS receivers on one of five planned routes from the Kunsthalle and headed south over the train tracks to walk in the shape of a single letter. Some of the walks were made more often than others affecting the density of the lines that formed the word.

After each day of walking the GPS data was projected onto the Stadt-theater to gradually reveal the drawing to the city.

On the last session of the last day we decided to head for a local park and improvise some drawings on foot within the perimeter.
