Metamorphose of a butterfly from an egg to become an imago is bizarrely beautiful. This art piece is aimed for an internal edification of WHILL Corporation, which develops and manufactures personal mobility devices. WHILL is a company which runs ahead of the industry and innovates new value so I wanted to express the sense of freedom and strength of an eagle gliding through the air. It is a bit scary to change the external look into something totally different. However, a butterfly changes its look and shape to survive and fly away. That is the identity of living matter.
