Win-Winの関係

ハンドルを回すと、小鳥がカバの背中の虫をついばみ、恍惚の表情を浮かべたカバがゆっくりと口を開きます。この作品は「歯車」と「カム」を使用しています。

Win-Win Relationship
When you turn the handle with your fingertip, a bird feasts on ticks on a hippo's back and the hippo opens its mouth gradually with evident satisfaction. This movement is made by "gear" and "cam".
