Did you hear the story about the three whales?....Well, well, well!
Did you hear the story about the cookie?....It's crumby.
Did you hear the story about the firetruck?....It's all over town.
Sorry, those are old jokes that pop into my head each time I hear the word "well". I even know some in french (As tu entendus l'histoire de l'assiette?...Elle est plate).
My son told me that every good village in minecraft needs a well. So I thought maybe it would be true in other settings. So my next project was little wells.
I made a large one, and then just shrank the center and re-used the strut and roof design to make a smaller one.
