Stephen Wilson's IntroSpection

"The installation enables people to interact with microorganisms and cells derived from their own body in a non-invasive way. The contradiction of interacting with these alien, unfamiliar life forms (which are nonetheless intimately connected with our bodies) focuses on the boundaries between self and non-self and the cultural interest in bioidentification."
