Esto, eso and aquello ... are these words interchangeable?

Question

Esto, eso and aquello ... are these words interchangeable? Do they all mean this or that? Or are there certain situations where it's better to use one of the words over the others?

Answer 1

There was another thread about aquello where the difference was explained, I think, pretty well.

Answer 2

I figured out the difference between esto and eso, but what is the difference between eso and aquello ? They both mean that.
