How to duplicate scene gizmo?

Hi all, I'm looking to duplicate the scene gizmo in Editor Scrip using C#. I know they already have it why would i ask to duplicate it? This is just me trying to learn more about Handles and gizmos in the scene view. Hopefully to be used later on in a Unity editor script I'm working on. I've looked through all the documentation an the Unity website(please don't just send me those link) but it leaves a lot of holes when trying to do something like this. Any help that you could give for this will be appreciated, thank you. PS. Dev's please don't be afraid to help also ;)
