An homage to Vilem Flusser’s text, Vampyroteuthis Infernalis, Bilateria employs the Klein Bottle as a form with which to inhabit the interstices between organisms and environments. The Klein bottle is a mathematical shape that, like the Möbius strip, merges interior and exterior, beginning and end. Here the form is simultaneously a leaky vessel and a projection surface for an array of found video material. Organisms and environments are mapped onto a single metabolic pathway where inside and outside continuously fold into each other in rhythmic pulsations.
