靈感來自於伊索寓言中的其中一則故事“國王長著驢耳朵”中的『樹洞』， 是一個可以讓人傾訴心事的地方，故事中的大臣為了守住國王的秘密而悶出了病來，就像現代社會一樣，總有很多情緒留在心底最後卻病成了心理上的疾病。
我們已樹洞為基礎造型衍生發展成黑洞，象徵一個可以吸收無限情緒的地方，配合持流體與聲音共振，讓使用者在視覺上得到回饋，抒發情緒。

The inspiration comes from one of Aesop's fables "The King Has Donkey Ears" in the "tree hole", which is a place where people can confide their thoughts. The minister in the story got sick from boredom in order to keep the king's secret, Just like in modern society, there are always many emotions left in the bottom of my heart, but eventually become mentally ill.
We have developed a black hole based on the tree hole, which symbolizes a place that can absorb infinite emotions. With the resonance of fluid and sound, users can get visual feedback and express their emotions.
