In the work Du Preez/Gui (2013), artist Nelmarie du Preez (b. 1985, South Africa) has established a ?collective? between herself and her computer (Gui), where they stand as equal actors in a performance-based artistic collaboration. This work asks how a human-computer relationship might be useful in revealing questions with regards to ?the self? constituted by ?the other? in the mapping of relation.
