Cystosepiment

This is the appearance of light through a piece of foam board, I inadvertently found that it looks very beautiful, like the appearance of the creature under the microscope, many cells together, and the light is yellow, but as the distance from the light source position is different, the colors are different around the, around some shallow blue, but not abrupt. Like many cells arranged orderly is not rigorous, very interesting, because of the difference of thickness, light through to different degrees, which makes it have the difference between light and shade.
