The offline workshop will be based on sensors and an interface that translates the physiological parameters of a tree into four lines of minimal poetry. Participants will start by observing the trees during a walk, then they will be introduced to the Tree Talker data collection system (sap flow, accelerometer, temperature and humidity of the trunk and the soil, spectrometer) and the translation principle and will create their own lines of text. The results of the workshop will be presented in the form of a grove of generative poem-trees on the web.
