Somnifer is a live image-editing software tool that transforms source images in an expressive clone-stamp spirit. It is built from autonomous editing agents and algorithmic brushes that move through a noise-driven flow field, sampling and redepositing textures, shapes, colors through shaped stamps. The image-making process is painterly in nature: a synthesis of vision, improvisation, and chance. Somnifer operates at the threshold between noise and pattern. Source images dissolve and re-emerge through layered algorithmic processes and human improvisation. The result is not instantaneous; it accumulates over time as few to hundreds of agents trace their paths, each carrying its own behavioral traits. The same system produces radically different visual registers depending on the artist’s choice of brush type, parameters, masking, and source material. The artist’s role is not that of a spectator but an instrumentalist: selecting, adjusting, interrupting, and steering the process in real time. Somnifer is not a filter or a generator; it is a performative tool where algorithmic behavior and artistic intention meet on a shared canvas.
