The Erasmus MC (the Rotterdam University Hospital) approached V2_lab about the realization of an artwork for the opening of their I-Space. The I-Space is an immersive virtual reality environment like CAVE and belongs to the bio-informatics department. It will serve as a facility with three-dimensional interactive projections for genomics and proteomics data and clinical imaging techniques. V2_lab commissioned Sonia Cillari and Edwin van der Heide to create a proposal for the content of the artwork. GATC / life explores our perception in a condition of extended body dimensions and lack of control. GATC / life is an immersive experience inside unities of life. The liquid multi-colored breathing membrane of the inside contains flocks of cells, particles and molecules having disordered human-like noisy behaviors. Our presence and actions can influence their configurations and growth.
