Project 2: How to Make Circles in Minecraft : Minecraft Spinning Staircase

One of the hardest things to make in Minecraft is something circulatory.   The main reason is simply because everything in Minecraft is square!  So how to turn something square, into a circle in Minecraft is a task all by itself.
My goal here was to make a circular tower, add a spiral staircase and then branch it off in different directions (as you'll see later).

The best way to do this remember this pattern, 1, 3, 1   Doing the blocks in this order will create half a circle.  kind of like this:

    1
3
3
3
    1


To give you a better idea here's what to expect when  you're done
       3  3  3
   1             1
3                   3
3                   3
3                   3
   1             1
       3  3  3


This will create a nice little circle to start off with.  If you want to make it bigger, just start adding numbers, just remember to make it an even pattern always otherwise you're going to end up with a crooked circle!
