Ferroflower
When light passes through a thin layer of ferrofluid subjected to a magnetic field, we can observe the formation of interesting luminous patterns. In this picture, we can see the light diffraction in this system observed with Mobius transformations, forming a hexagonal pattern. More about this picture can be found in our research about light diffraction in ferrofluids subjected to magnetic fields: "Observing Dynamical Systems Using Magneto-Controlled Diffraction"
