Holograms

 
Holographic material stores images that can be recreated when light strikes the material.  Multiple images can be stored in the same space, each offset by a slightly different angle of recording.

People can be like holograms--multiple attributes in the same person.  From how someone acts in an emergency, you can deduce dimensions of their character.  Seeing someone interact with a child, indicates how they operate with other people. 
What are the snapshots in your own life that divulge the aspects of your character?
Finding a wallet on the ground.  Dealing with a friend who needs assistance.  Grappling with a decision to get up to face a difficult day or to roll over and go back to sleep.  Taking a break to enjoy a sunset.
If light passes through a part of your being, what does it reveal about the essential you?
