For over thirty years now, Tjebbe Van Tijen has been creating 'visualisations' of ecological matters, urban conflicts, alternative culture and historical subjects. Current research projects focus on ‘literary psycho-geography’, aerial bombing, mapping human violence, visual language, media history and education systems.
A recent interview, in OPEN (NAi Publishers) by Geert Lovink, highlights his 'Unbombing the World' and 'Ars Memoria' projects and gives an insight in his thoughts on collective memory.
The project intersects with recent public debate in Copenhagen about air pollution in the city. In collaboration with Senior Scientist Jørgen Brandt from The National Environmental Research Institute in Denmark a first prototype is developed for making an indicator that can be placed in the city and display local levels of pollution as well as pollution forecasts on individual streets. The project holds an open source script for displaying data from the Internet in a variety of forms.
