Biodegradable Trend-Tracker Capsules
Single-use, biodegradable capsules that contain a nutrient blend. When discarded (preferably composted), they release a specific dye that colors any nearby organic material (grass, leaves, etc.) in the latest trending color of the week, providing a fleeting, localized environmental expression of the current AI-dictated fad. This makes the environmental impact immediately visible, in a hopefully humorous way.
