Minecraft: The Eye of Sauron

So after making the monster trap I had a lot of cobblestone left over so I decided to make a tower.  I couldn't find a spot that I liked to build it on, so I decided to make an island.  

Next I laid down a basic outline and started building.  The tower is about thirteen by thirteen and is as circular as I could make it with cubic building materials.

Next I just filled the rest in by jumping repeatedly and laying down blocks, creating straight vertical lines.

 

At this point I decided to make the tower a little different then I had originally intended, so I took some inspiration from The Lord of the Rings and built this.

 

I then made a giant floating glass sphere and, using obsidian for a pupil and magma for an eye, I transformed the sphere into a pupil.

 

And there you have it.  The tower makes a great landmark as it is as tall as the game allows for, and has a massive ball of fire at its top.  Next I am going to go exploring and documenting any interesting landscapes that I encounter.  If anyone has any build suggestions leave them in the comments section and I will try to get around to them.
