Happiness 205 is an architecture of cheap drug induced happiness in a set-up where the human performer and the performative matter compete for – or share – the performative role. The installation is made of canned dime-store cotton candy in pastel colors and in big quantities: 205 cans. Exposed to oxygen, the cotton candy shrinks visibly over time. In irregular performative interventions the lids of more and more cans are gradually opened, causing the matter to perform: the cotton candy will retract and shrink to a small size, a miniature version of the shape of the transparent plastic can. The human performer reacts to the matter's own performative interventions and rearranges the cans in the space, creating an ever-changing landscape of cotton candy and plastic and a permanent hand-over of agency between the performer and the matter, almost a dialogue.
