Moisture levels inside the soil silently trigger words to appear on the laptop like online messages. If your plant could talk to you, what would it say? A potted plant is entirely dependent on its human caretaker. It would say whatever it takes to ensure you care for it, even manipulating you if necessary. Your plant would probably be rather flirtatious too - a plant's primary goal is to reproduce.
Viewers are hesitant to interact with installations (especially one that's telling you to chuck water all over a piece of tech), so the plant patronises you, calling you silly/cute/shy for not wanting to water it. It coaxes you in, promising to show itself if watered. Once watered, it goes fuzzy, happy, orgasmic. It rewards you by revealing itself: a 3D scan of the plant appears on the screen, with the pot removed to display its roots. After, it essentially breaks up with you - telling you to move on to see other things at the exhibition. It asks you to meet again next week.
