Echoes" delves into the idea of liminal space, which lies between perception and meaning. While we use light waves to make sense of space, termites employ mechanical waves. The work connects these different stimuli - sound, space, and scent - in a transmodal experience. In this VR installation, a mound-like structure floats in darkness, causing disorientation. Using a microphone, the user can create echoes in the virtual space and manipulate the sound effects through movement in the liminal space. The olfactory artifact is used to guide the person through phase transitions with the aid of scent and sound. "Echoes" offers a captivating glimpse into the complexity of termites and their perception of space, and how this overlaps with our own.
