An web app that lets people erase the map of a city by walking its streets. This experiment is in the form of a web-based application designed and programmed using PHP programming language, OpenStreetMap (OSM) and Leaflet JavaScript library. Using the simple map-like interface, the participant/player can erase the map of Utrecht along his/her walking trajectory. While walking on the streets of Utrecht, the walker leaves behind a trace of permanent erasure on the map. 

This web app was presented at the Play | Perform | Participate Conference (University of Utrecht, 2015) as a social strategy to mapping.  Conference members could experiment with the app after which it formed the base for a discussion about critical cartography.
