When we are nostalgic for certain pasts or futures, we may start hoarding or intensely use digital technologies to bottle time up, yet, if these objects or "bottles" could speak, what would they say about how we are dealing with time that has been, and will be lost?

This introduction was part of NOSTAGAIN NETWORK's Time in a Bottle symposium and research-creation showcase featuring works related to nostalgia by students, scholars, and artists. Workshops, art installments, presentations, debates, and discussions allow for various levels of interaction, reflection, and reception.
