how its done: suspend nano-particles of iron compounds in a colloidal solution of water, oil and a surfactant, then when a magnetic field is applied to the fluid, the particles of iron compound inside align to it. Once that happens, the fluid becomes a fluid-solid. I think. Little shaky on the science, but love the eerie 3D art!
