Glocal heterotopias is an initiative raising from the Callús area, a catalan digital town close to Barcelona, Spain. The goal of the project is to promote and disseminate around the world projects that make us realise that other spaces or other world are possible. Projects that tell us about the heterotopic space as a tangent exit to the system. Projects that use the network for coordination purposes and such that this results in an actual answer in the physical world. Here there is space for any initiative involving digital towns, e-democracy, hacktivism, free software, tactical media, artivism, P2P, ... To include a project you just need to be accepted by one of the participants called "connectors". It is also possible for you to become a connector of other projects, so that the project network can be extended.
