In this artwork, an attempt is to materialize intangible light as tangible which is visible and static by giving a concept of maintaining the shape of light. The materialized light exists in a three dimensional world as one structure like a preserved lifeform, or a sample as an observation target for research. A ray of light is confined in a sphere, and repeats 10000 reflections based on the rules of physics. The reflection result is generated by the computer as three dimensional data(to be specific, each vertex of lines and points). The data is converted as 2D bezier data by outputting and using custom csv and jsx files. This converting approach is an important process in this artwork that the data generated by physics simulation executed in a computer is for to materialize as high resolution in the NFT world as possible.
