As you step inside, you’re greeted by a space enveloped in natural materials from earth and wood. Children communicate by touching the walls, enjoying textures of soil paint, natural stone counters, brick tiles, and more. They also play on touch-panel monitors embedded in the walls, simulating growing and harvesting vegetables. These experiences, combining real materials with virtual interactivity, nurture children’s sensitivity and wisdom through play.
