《回溯》是一件藝術家對於現下科技發展的批判。在作品中分成兩個部分，第一部分為威利以第一人稱角色於資料超載的遊戲世界中探索。快速、永恒的挑戰與變動追求著遊戲最終的目標與勝利。第一部分藉由遊戲提出了許出關於理解人類及存在的問題。海德格曾說，科技的發展是為了讓人免疫於改變、避免意外的驚擾。而今日的科技則藉著愈發簡單便利的途徑讓人分神，一方面讓我們驅逐無聊，另一方面也屏蔽了我們與生俱來自由思考的機會。

作品的第二部分則交織了傳記、歷史及哲學的思考。當我們手指於線上動作每個click，我們將會在線上留下我們的足跡，讓雲端歸類統計眾人的行為表現，再行規範形塑個人的未來表現。遺留在線上的痕跡，同時既屬於個人，亦不屬於你個人，這件作品正是搜集了這些數位的斷簡殘篇，述說著我們分散的線上生命經驗。

Recall is an artist’s criticism to the technological advancement today. The artwork is divided into two parts. First is Wylie explores in a game world overloaded with information from the first-person perspective, in pursuit of the ultimate goal and victory in the game in the fast, eternal challenges and changes. The first part is to propose questions about humanity and its existence via game. Heidegger once said that the development of technology is to make people immune from change and free from the disturbance of accidents. Yet, the technology nowadays distracts people with its ever simple and convenient means. On one hand, it helps us to expel boredom; on the other, it blocks us from the opportunities to think freely we are born with.

The second part of the artwork are intertwined with biography as well as historical and philosophical thinking. Every click at our fingertips online leaves our footprints online, allowing the cloud to categorize and calculate people’s behaviors, so as to regulate and shape the future performance of individuals. The traces left online are personal, but not of your own at same time. This artwork collects all these digital bits and pieces to talk about our distributed online life experiences.
