此作建立於藝術家對於「思維」的思索。一個常人一天約有2萬次的思緒進出，思維是很難去測量或是接收的，但它可以直截的引導我們的生活直至死亡。數世紀以來，藝術家、科學家和哲學家不斷試圖去補捉人類的思維。在此件作品中，鄭佳喜以祖母為標的，試圖以許多不同媒材去探索、紀錄並視覺化思維。

根據藝術家所說，此件作品是以石塊作為儲存器的比擬。石油、石頭經過數百萬年的累積，記錄下自然的韻律，這是最長久也耐久的儲存裝置。而當前的科技社會創造出許多史無前例的景觀，卻鮮見屬於人類的思維的儲存所。此作亦關注思考及探討思維儲存的可能性及其如何作為一個年代的人類基礎心理狀態被傳承下去。

The artwork is built on the artist’s contemplation of “thought”. An ordinary people has approximately 20,000 thoughts in and out. A thought is something hard to measure or to capture. Yet, it can guide our living directly till death. For centuries, artists, scientists, and philosophers have been trying to capture the human thoughts. In this work, Ka Hee JEONG uses Grandmother as target to explore, to record, and to visualize thoughts via different mediums.

According to the artist, the artwork takes stone as a metaphor of storage. Petroleum as well as stone takes records of the nature’s rhythm through million years of accumulation, which makes it the longest and the most durable storage device. The society of technology today may create many unprecedented landscapes, but rarely a vessel to store human’s thought. The artwork concerns about thinking and investigating the possibility to store thought as well as how the basic mentality of the human in a certain times can be passed on.
