Liquid crystal:
Since liquid crystal material conducts electricity, it can be imaged on the molecular level by Scanning Tunneling Microscopy, or STM. In the picture above (by J. S. Foster and J. E. Frommer) the crystals look relaxed, and opaque. Below, in a picture by D. Smith, H. Hörber, Ch. Gerber and G. Binnig*, where more voltage has been applied, the crystals are excited, and thus transparent because the ends have bunched up:
* G. Binnig along with H. Rohrer invented the STM in 1985.
