Untitled (Domino Theory) concerns the vulnerability of systems brought about by human action, especially anthropogenic climate change. I create a state of self-organized criticality to explore interactions between environment, system and observer. Migration can result from flooding and political turmoil, consequences of global warming. To exemplify this, I suspend a platform precariously upon which dominoes (“homes”) are positioned along migration routes on a map. Viewers must avoid toppling the structure. When viewed through AR, a video is triggered of floods toppling “homes”, suggesting how one’s actions influence the configuration of the entirety, key to our ability to ameliorate environmental disaster. — Ellen K.
