A collaboration project with Lieke Vernooy, Jasmijn Muskens, Fabienne van Steensel and Irene Wu. Together we wanted to break the tunnel vision of the passersby in the Holland Spoor area. In order to do so, we had to grab their attention from their daily routine to the environment of the moment. By the concept model of Lieke we fully designed and created stones that produce sound. The sound is based on disturbed soundscape of sounds that are recorded on the place itself. By placing these stones on location an absurd situation was created and therefor broke the daily routine of the passersby. This one day pop-up of the three stones has a transiency only captured by (moving) image and in the memory of passersby.
