This is not for the complete novice, but someone with a moderate amount of knowledge in geometry and power tools and a little carving can make this in about 6 hours.
NOTE: If you do not have wood burning tools, I list a alternative method to the burning in step #5
NOTE #2: You can apply this method to many other types of designs and get a nice finished product!
Tool list :
Wood (preferably 1 x 6 in. by at least 38 inch)
Carpenters square (big and small type helps, but the small type and a good straight edge will do)
Jigsaw or bandsaw or scrollsaw
Circular saw (optional but will save mass time and make a nice straight line for taking off horizontal excess)
woodburning / pyrography source (optionally a solder gun)
wood chisels or Dremel or * maybe razor blades if your risky (be extremely careful if you use razor blades)
Sandpaper / palm sander
Black spray paint (quality of paint isn't really a issue, I opted for the cheap dollar store stuff)
Cardboard (preferably as long as your piece)
Sorry for the lack of extensive photo documentation of every step here. I did not think do to a instructable until after completion, I did however photo document the general steps so that helps a lot, you should be able to get the gist of what I did here.
Step 1: Mapping Out the Image
First I sought a official looking logo off of a Google image search. Then I mapped a scaled version of the logo on a sheet of grid paper. Over all this was rather easy given the pixelated style off Minecraft related items. The only place you might experience any trouble here is the creeper face in the letter "A" some of the lines fall on half pixel marks, you should be able to see it pretty easy in the picture.
