These are the design patterns as defined by the Gang Of Four (GoF) in their seminal book "Design Patterns: Elements of Reusable Object-Oriented Software" and can be found on Amazon (non-affiliated link) . Some of the things I'll be posting will be related to the various categories of design patterns (as defined by the GoF): Creational, Structural and Behavioral.

For those following along, I'll have the code for these examples ...
