A project to map Barcelona by bike by Martha Skinner has caught our attention. BiCi_N is a project based on the GPS tracks collected by riders of the new Barcelona rental bikes. Barcelona has this great rental schema called bicing, where frequently everywhere in the city large bike racks are placed with parked bikes and anyone can just grab a bike and explore the city, return it to any other station you wish.
The project BiCi_N in still in its test phase at not yet up and running, but some first tests haven been under way. A two week trial period took place last year and some material of this is now online.
