O_t_LIA is a reflection on the development of human perception, based on observations made during the 6 months following the birth of my son. It is about the transition between one world and another, an attempt to imagine living in a world that can be seen, heard, and felt without words or concepts, and the unseen world (wireless communications, neutrinos, etc.) that surrounds us. It is about the shaping of human experience by experienced humans, the wiring of the brain, and waking up in the middle of the night and not knowing where, or what, you are. This piece is dedicated to my son Luca, as a celebration of his journey to be here with all of us on planet E.
