The Butterfly is a transparent, social climbing magnet for children. The elegantly curved wings with their twisted climbs invite climbing try-outs again and again. Thanks to the transparency of the Butterfly nets, the children can see each other and communicate across the Butterfly, and from ground level to top. This adds social interaction and a possibility for cooperation and sharing. Climbing the Butterfly trains cross-coordination and balancing techniques, which stimulate the child’s ability to control movements, and ultimately to move confidently through the world. The visible heights add thrill. There are faster and slower ways across and up into the Butterfly: Curved Climbers add faster access to the top frame. On ground level three Optic panels with visual effects attract attention and discussion as children get their sense of wonder intrigued by the moiree effect patterns: they look different depending on how children focus, which adds to logical thinking skills.
