There is holography representing "change in quality" in metamorphoses. Holography does not change shapes but changes quality. It has an unexpected effect where a solid and a concrete object which appears to be able to be touched and is transformed into a three-dimensional image which is a chunk of lights which can not be grasped. This is a change in the material and colors, and a magical metamorphosis by optical interference.
