The handprints in the Lascaux Caves are one of the earliest artistic origins of mankind. These murals reflect the awakening of primitives' self-consciousness, since, through murals, they tried to understand the relationship between humans and nature, life and death, etc. In this project, we want to complete a digital mural to reflect on the current relationship between human, technology and nature.Specifically, the natural texture is generated by the algorithm, and then the final pattern is formed by human artistic processing.
