What is the definition of Breathing Project?

The 'breathing project' is like a high-tech, high-stress art installation where scientists (or so they think) have somehow managed to create a machine that can mimic the very process of human respiration. It's basically a glorified, futuristic air purifier with a side of existential dread - because who wants to breathe in some artificial life?
