This one is really easy and looks absolutely wicked. I was able to finish it by midnight and that included designing it as I went along and taking the photos, so I reckon you could probably make this in less than an hour... if you have the stuff to hand, that is.
Mad Eye Moody was one of my favourite Harry Potter characters. Brusque but brutally honest, tough and resourceful, with a compassionate side, he is the wizarding world's best known cyborg as a result of his prosthetic magical eye which can rotate 360 degrees and see through almost everything (including walls, doors, invisibility cloaks and the back of his own head), hence the nickname "Mad-Eye".
Please take a moment to make this mad eye, in his honour and wear it with pride. Unfortunately my mad eye, while looking the part, actually impedes your vision, being more of a patch than a bionic eye, becuase the whole magical thing was beyond the scope of this instructable.
Happy mad eye making.
If you like making stuff from junk, then why not have a look at my site dadcando where you'll find a few really nice making from junk projects on there which you should have fun with.
Also look out for my instructable on putting your self in the picture, where I show you how I made my final poster image (coming soon).
