A pure-fragment gravitational-lensing study: a procedural starfield behind a compact mass, with every ray bent through the source-plane map rs = r − mass/r. Where that fold collapses toward the source origin the background stars pile up into an Einstein ring hugging the shadow, threaded by a bright photon ring. An inclined accretion disk arcs over and under the black silhouette — Doppler-brightened and blue-shifted on the approaching edge, dimmed and red-shifted on the receding one — while a second lensed arc rises over the top the way light from the far side wraps around. Move the hole with the cursor, scroll to pile on mass (widening the ring and shadow), and press to intensify the whole apparatus. This is deliberately different from the compute-particle accretion sketch (#42): no particles, no simulation — the entire image is analytic UV distortion in one fragment pass.
