deep zoom liquid crystal images part 2

Please maximise the image below to fill your screen. The image has been stitched together from hundreds of polarizing microscope photographs. It shows a 'liquid crystal cell', or two pieces of glass separated by 10 microns (10 millionths of a meter) and filled with liquid crystal. The cell is approximately a centimetre wide.

Several different types of liquid crystal have been filled into the cell, in order to make it look pretty! Can you tell me what you think is going on?

There is an artefact at the bottom where the computer program was unable to stitch the images properly together. If you have experience and would like to do a better job than me at stitching, please get in touch and I can send you the source images!
