Wander, root & grow

Unearth the secrets of the green kingdom. Investigate interactive dioramas of the grasslands, forest, and desert: befriend chattering animals, spark wildfires, spin through seasons and time, and see how flora and fungi germinate, pollinate, and decompose.

  • New: In the grasslands, graze with guanacos, whirl never-ending winds, and start smoldering fires that spark new growth.
  • In the forest, burrow with badgers, hatch an acorn into a mighty oak, inspect root systems, and crash clouds till lightning strikes. But beware the wandering bear!
  • In the desert, slurp from an oasis, jump with jerboa in the cool of night, and see how abundant life adapts to this tough habitat.
  • Original artwork by Marie Caudry.
  • Algorithmic animations yield surprises and reward hours of open play.
