The bright flash occurs because when sperm enters an egg it leads to a surge of calcium which triggers the release of zinc from the egg. As the zinc shoots out, it binds to small molecules which emit a fluorescence which can be picked up by camera microscopes.
Shibori is a Japanese technique of creating designs in dyed fabric. It is a dye-resist technique, using items that bind the fabric to create areas where the dye will not penetrate. Depending on the materials used and how the fabric is bound, the dyed designs vary from random splashes of color to highly symmetrical patterns.
Woven Shibori is a process of weaving and resist that Catharine Ellis developed in the early 1990's and has continued to evelve both technically and artistically. Traditional Japanese shibori uses a variety of means to compress cloth before it is dyed including stitching, binding, folding, pleating, ect.he stitched shibori was the inspiration for woven shibori.

When the stitches are completed they're used to gather the cloth tightly. Then the cloth is dyed.
