Mission by Trismegisto 'Herbert' Taraxi
What would a city sound like through plant ears? What would a city sound like if humans could hear what plants 'hear': changes in light, moisture, wind, tactile sensations, chemical signals, sound…
Alternatively: what humanly audible sounds should we amplify/subdue to experience a plant's sensory spectrum? Can we make music that can be enjoyed by both people and plants?
NOTE: this mission can be a speculative design exercise or an engineering challenge, depending on your skill and interest level.
