I stole some speakers at work today, and ended up listening to an interview with the people responsible for this project:
SPCMKR facilitates and documents space exchanges, providing a site through which to organize a gift-economy between users. The web-based component of the project provides an interface for locating and contributing resources, arranging for temporarily inhabiting surplus spaces, and documenting both the exchange and the activities that occur while in residence. SPCMKR is a way in which to proliferate small everyday surpluses, allowing for flexible, friendly opportunities, rather than engaging with government or institutional power structures. SPCMKR should be understood not as a residency to which you apply but rather as a network in which you can contribute and benefit from the exchange of resources.
