a playful systems-science pond
Guppy Vitality Lab
A cozy anime-style aquarium where you steward a pond of cute guppies. You don't boss the fish around — you stir the water, tune the conditions, and watch schools, roles, and little pathologies emerge.
🧪 A playful systems-science toy. The on-screen vitality numbers are for fun — but one thing is real: the Live CE meter runs genuine causal-emergence math on the pond and reports it honestly (it stays small). Not a clinical, safety, or operator-state evaluator.
A cozy aquarium sandbox where you steward a pond of cute guppies.
You don't command individual fish — you perturb the pond and tune conditions, then watch schools, roles, and pathologies emerge.

What you can do
- Stir the pond with events — drop food, cast a shadow, add a novel toy, drop a rock, or whip up a storm.
- Tune conditions — Curiosity, Danger, Turbulence, Togetherness, Thinning, and Spread.
- Nudge the system toward exploration, recovery, diversity, or pruning — then watch it respond.
- Switch the scale lens to see individuals, schools, neighborhoods, the whole pond, or just the troubled spots.
- Try a scenario — Calm Pond, Storm Recovery, Overgrowth, Autoimmune Pond, or Discovery Bloom.
- Watch the Live CE meter — the one real measurement. It asks whether the group of fish predicts its own next move better than the individual fish do, and moves as you tune the pond. What that means →
