As much as I'm a fan of still photography, a static image can't capture the essence of fluid LC phases. To truly understand liquid crystals, you have to see them in motion. I have recently started to experiment with capturing movies of liquid crystals, as viewed by optical microscopy. Below is one of my first efforts: a commercial mixture of PCH derivatives being cooled from the isotropic phase into its nematic phase.
