Memory Beast was a series of experiments in multispecies collaborative storytelling. A new tool was created, a memory beast, a holotype representing our ideas of specific species, based on memories and drawings collected in participatory research. The fabricated memory beasts, placed next to their biological counterparts, made visible the conflation of living species with personal memory and cultural imagery. Using this new tool, implanted with sonic recordings of cows, the beginnings of an interspecies pidgin language was developed. Memory Beast imagined and enacted new pathways to finite flourishing on a wounded earth, planting story seeds for alternative realities.
