Stuff about code has a great Minecraft tutorial up on their site.
I have had this idea of creating a 3d graphics turtle in Minecraft for a little while so one Sunday morning while I was waiting for the boy to finish a swimming lesson this is what I did.
The Minecraft Graphics Turtle allows you to use the Minecraft world as your drawing studio and unlikely most graphics turtle’s you arent confined to 2d space, you can go up and down as well as left and right, and when your master piece is finished, you can walk around it!
The MinecraftTurtle is really easy to install and use, you only need a single python module (minecraftturtle.py), which needs to be copied to the same folder as the minecraft python api (minecraft.py, connection.py, block.py, etc), so if your using a Pi, its usually ~/mcpi/api/python/mcpi.
If you want to get started quickly through, I would download the complete code from my github, as it contains some examples and all the files you need to have go.
