This week Swapna and I finalized our proposal, and developed the bill of materials, timeline, and system diagrams necessary to complete the project.
Short: A coin-operated responsive plant that rotates to acknowledge human presence and a visualization of the CO2 in its environment, that plants do the work of converting to human-breathable oxygen, a service people have the option to pay for.
Long: Our project is meant, in part, to prompt people to think about the work that plants do regulating our environment and making it habitable, and what it means to put monetary value to this in a capitalist society. It is also an exchange with a non-human, generally immobile, but living being, that involves you communicating with it via your breath and physical presence while it communicates through respiration and the representation of data. We want to bring forth the way you are each affecting the surrounding environment and sensing each others presence in difference ways.
