IDEA: A program to make a graphic of any file

An interesting idea I once thought of, a program that takes ANY data (or just certain data other than image data for the time being) and converts that data into an image of some sort. I think it would just be interesting what kind of random images could be made doing this.

that's too easy, imho. in real-mode dos you could do a memcpy from the array extracted from the file onto the screen. in any graphics api it's a matter of getting dimensions and plotting points.
