You forgot to water the plant. Instead of seeing yellowing leaves, you see a cute plant-shaped pet on a tiny screen, looking sad and dejected. Maybe that'll give you the push you needed to grab the watering can. As you pour water into the soil, the plant pet on the screen gets excited and happy. That's the idea behind OATs, or Object Agent Twins—micro-agent AI avatars on tiny E Ink displays designed to pair with everyday household objects.
