An interactive, browser-based tool for exploring gravitational lensing phenomena. The software implements rigorous mass models, including point-mass, NFW halos, elliptical halos, and cosmic void profiles, allowing users to visualize lensed images and critical curves in real-time via a live web interface. While the physics is strictly grounded in these models, the lensing effects are purposefully exaggerated to highlight phenomenological features for educational clarity. It is designed for professional presentations, scientific outreach, and teaching.
