The system creates possibilities through not only the on the module creation itself, but also on how the created modules are assembled to accomodate certain activity needs.

It is seen as a potential to create a fluid urban interior by hijacking existing city's flow and relations, making the street vendors as the main actors that enables and enriches the liveliness of the city.
