Heartwarming Cactus is an interactive, bio-digital emotional support installation inspired by the symbolism of plants and CBT-informed self-reflection. Instead of treating emotions as something to “fix,” it offers a gentle space where users can externalize stress, notice patterns, and practice small acts of regulation.

At the center is a digital cactus that visually responds to a person’s inner state. As negative feelings accumulate, the cactus gradually weakens; when users process and release emotional “weight,” the cactus recovers. This slow, readable change transforms invisible emotional strain into an observable living metaphor—making care feel possible in daily life.
