The Mysterious Core (365) is a generative artwork that creates a digital image of a new sculpture daily. The work utilizes an automated set of instructions to construct each composition with AI-assisted imagery. Reben begins this process with a framework that the artwork uses to generate its own imagery. Each day thereafter, the artwork instructs itself to create based on what was developed the day before. Parameters are embedded that contextualize sculpture as an art historical dataset, encouraging the compositions to appear as three-dimensional, spotlight objects situated on a plinth. The Mysterious Core (365) serves as Reben’s own commentary on how machine learning constructs and understands art, giving the artist the opportunity to remove his preferences and reveal what AI determines as “good” and “artistic.”
