+Hypha’s practice is situated across many topics that are present in the theme of _Adaptive Reuse & Creative Misuse_. Drawing from our collective experiences, histories, and methodologies, our goal for the micro-residency to investigate how notions of digital infrastructure can be reused, reinterpreted, and reconfigured, to realize a kind of public space. Our approach to this theme will be composed of a few, very preliminary, subjects that will ground the residency: the situated histories of digital infrastructure, the implications of [[protocols]] for publishing ([[Hypertext]], [[RSS]], Peer-to-peer) in defining public spaces, and the possibilities of cooperative approaches to maintenance and repair. Our intent is to make the process of this investigation public through online tools mapping our thinking about the theme (Open channels in Are.na as one example) and cultivating a Digital Public Garden as part of Hypha’s contributions to the initiative (a resyndicatable adaptive online notebook). The outputs from the micro-residency will be a written contribution to the [_Field Guide to the Digital Real_](https://www.are.na/from-later/field-guide-to-the-digital-real) and a micro-website containing the synthesis of our investigations and our evolving practice. The outputs will be textual and visual, and draw from our collaborative practices as a cooperative. They will explore ways to represent relationships with existing and emergent technologies within our communities. Through our micro-residency we will capture a poetic interpretation of the theme and provide prompts for institutions in the city on how they could reconfigure technology to create radically creative platforms.
