Memorial Hall / Artificial Life Device

Tierra Specimen Aquarium

A small observation tank where artificial organisms multiply, disappear, mutate, and leave traces.

The tank is an exhibit. There is no victory condition, no score, and no final answer.

Visitors may stir the tank, add nutrients, lower the light, and read the observation log.

A Living-Like Display

The tank is not a preserved specimen. Each visit can produce a slightly different population, with dominant lineages, sudden declines, and small mutations.

No Score, No Ending

This is intentionally not a normal game. It is an exhibit for watching change, causing a small disturbance, and wondering what counts as life.
