Mapping in momentum is a collaborative project which aims to provide a cartographic provocation for walkers, one that will influence patterns of walking behaviour and develop new reflections on the experience of walking. The project follows the philosophy of Felix Guattari, in particular his conceptualisation of cartography, in which the map ‘loses its primary vocation of having to map the Territory’, and ‘the distinction between the map and ‘the thing mapped’ starts to disappear’ (Schizoanalytic Cartographies 2012: 35, 268). Drawing on Guattari’s idea that a map is a tool which initiates thought and action in the world, Mapping in Momentum collates postcards that exhibit an array of performative journeys that began with the motif of a map. When postcards are received they are displayed below. Any contributions to this project (postcards or e-postcards) are very welcome. Please get in touch for more information or send a postcard to me at the School of Geographical Sciences, University of Bristol, or to Nina.Williams@bristol.ac.uk.
