This perspective evades science.

Networked agency destabilises traditional orthodoxies of capacities of art in order to articulate a sense of dispersedthought through challenging notions of representation, embodiment. Unlike traditional sites for communication andconfronting materialism, accelerating and smoothing social cultural exchange, digital platforms rely on actions andengagement and most importantly, demanding participation in conversations to shape not only the social and culturalthese open systems of collaborative engagement. This has environments, but also the spatial environments.

Technical Specifications Diagram for Terra(socio)sonica 4.2 ORGANTRADER2010 organtrader2010 is a novel mixed reality interface that allows for the transfer of real CT scanned organs into augmented reality and Second Life. Using the metaphor of organ trade to allude to Figure 1. Second Life view of virtual ‘shadows’ from physical data traditional gallery hierarchies, organtrader2010 allows the
participant to donate, sell, buy or steal virtual organs acrossplatforms including an interactive mixed reality system, standardSecond Life interfaces and mobile platforms. organtrader2010uses the organ trade metaphor to question the meaning ofownership and the relationship between content and property. Inregards to (unregulated) machines of production and thesubversion of power hierarchies, organtrader2010 examines theroles of media artist/supplier, gallery/distributor andparticipant/trader. In doing so, the project exploresdeterritorialisation of the body and posthuman identity in mixedrealities.organtrader2010 uses a narrative representational structure in amixed reality context where a participant, wearing a cameramounted HMD (head mounted display) can transfer real CTscanned organs to an augmented organ ‘trader.’ This augmentedSecond Life avatar can exist in both physical and virtual spacesimultaneously, so when the participant hands over one of theirorgans to the ‘augmented trader’ they are also giving their organsunsuspectingly to the ‘in-world avatar.’ This avatar is linked to anetwork of organ trader avatars that all have ownership Figure 4. Technical Overview Diagram for organtrader2010permissions to clone and steal organs from the augmented traderand sell them to other Second Life avatars. The system uses an XML RPC to link an augmented reality application with Second Life via a PHP server. This pipeline allows for a method of real-time transfer of 3D visual material, linking the body with the augmented and virtual representations of itself. The use of real CT scanned organs with fiducial marker and proximity tracking adds to the viewer’s experience of agency within the processes involved in the simulated organ trade and in the process of media art creation, display and dissemination. 5 SYNCRETIC POST-BIOLOGICAL IDENTITY At the recent First International Conference on Transdisciplinary Imaging at the Intersections between Art, Science and Culture (TIIC) Roy Ascott gave a keynote in which he described Syncretism as a possible method by which to classify mixed reality interaction . He used Second Life as an example of a metaverse that allowed for an embodied syncretic participatory experience. Second Life, like all virtual environments uses an avatar (agent) to navigate users through the space. While these are usually controlled by the user (avatars can be automated and left on their own, plus there are bots being regularly created and used), they function as independent to their ‘master’ and are therefore autonomous. Returning to the example of Facebook, this can also be said for user profiles on that platform. Who we represent Figure 3. Installation setup for organtrader2010 ourselves as on social networks is not necessarily a true articulation of our identity by any means and therefore it isAs mentioned above, the organs in organtrader2010 are obtained autonomous. Avatars represent a transient, continually alteredthrough real CT scans and are made by converting data into a 3D identity, usually that of its author and acts as an agent, throughmodel, then converting this model to Open Scene Graph. They are which users can engage with virtual platforms. This becomesthen included in a Python-based application that uses the particularly interesting in unique autonomous systems whereOSGSWIG python wrapper for the ARToolkit to enable the participants can physically interact with a virtual deterritorialisedaugmented reality system to occur.
