A mix of algorithmic art and generative AI creative upscaling. Starting with an algorithm to depict flow fields and spherical obstacles, the output is creatively upscaled with a marbling effect. 

The spheres are reminiscent of those found in my Spheres of Influence drop on Nifty Gateway, but rather than packed together, they are placed sparsely and block/repel the flowfield particles. For more information on flow fields check out this article by Tyler Hobbs. A generative upscale process applies a marbling texture to the lines drawn by the flow field particles.
