Small min map of local area of larger map

So I was trying to make a mini map that shows a local view of a larger map, I would like to only show a portion of the map and then make the map link to a full screen version.

I found the following tutorial examples but I'm stuck on limiting it to the circle area or a square in the top right corner.

Hiding the whole map and just displaying it it the corner circle or square is the main question.

Also some idea of making this clickable a displaying the whole map? Anyone have ideas about how this would work?

Few years back R0J0hound Posted a mini map that does something similar to what I would like to do:

I made a simpler version here that is closer to what I want to do:

Check out this demo:

It only works with rectangular objects. If you want to display any objects (with textures, different shapes, angles), you will have to paste them, it's a bit trickier, here is an example:
