Are these fallen leaves, or tadpoles? Perhaps they are tadpoles that have metamorphosed from fallen leaves, and are now enjoying their swim! They take pleasure in the natural surroudings, doing their best to become part of this beautiful forest, they cannot wait to become amphibious frogs so they too will be able to explore further in this handsome forest shrouded with green light. This work is designed to correspond to, as well as further the conception of the “Path of Evolution” previously constructed by the National Museum of Natural Science. By reviving the symbolic images of ancient creatures, the Taichung municipal green belt will be revitalized with a sense of energy, value, and spirit.
