Reflection is a design principle that allows a system to have
a representation of itself in the manner that makes it easy to
adapt the system to a changing environment. It has now
matured to the point where it is used to address real-world
problems in various areas. This principle has been also
identified as a pattern of software architecture (PoSA) [1].
This paper presents a non-software examples of the
Reflection pattern. We present a simple and household
example and an example in the immune system. We believe
our work helps understand the intent, structure and
consequences of the Reflection pattern.
