Lost and Found invokes language itself as a cultural construction that contains and generates worlds. It continues Hiller's focus on language groups and their speakers but now includes languages (some endangered and vulnerable, some extinct) that might be leaving the archive to be spoken in the present and the future. As if to reinforce the physicality of these possible returns and survivals, a flexing green oscilloscope line tracks the sound made by the voiced plosives, fricatives, and aspirations. This moving wave also acts as a synecdoche for the arena of technology; although the production of a prevailing and flattening culture, it also operates as a platform used by the excluded and the marginalized for agency and expression. Technology allows the voices of the dead to be heard. On being heard, these voices return to the living to be mouthed, to articulate the particular mappings and experiences of the worlds that these languages describe and contain.
