There are many ways to create normal maps; Basic normal maps can be created pretty effectively straight from images or height maps using programs like Crazy Bump [link] or Ndo 2 [link] The most effective way is to bake from a high poly mesh or sculpt. You can bake maps in most 3d programs these days, Maya [link] and Max [link] been the best in my opinion. xNormal [link] is also a invaluable program for baking normal maps. There are many articles and tutorials around the net. I suggest checking these sites out for info;

I tiled a generic scratched texture for specular which i stored in the red channel of one of the hologram textures. I didn't bother with any unique spec maps this time
