Alexander-
It is a Normal mapping tutorial that uses perpixel lighting to shade. If you read the tutorial you see it 80% normal map generation, and 20% applying the perpixel shader... hehehe you wont see the blue texture unless you open the tutorial... its not a texture you are supposed to see in screenshots, its the shading. The perpixel lighting uses the normal map to create the perpixel shading...every object you see has normal mapping AND perpixel lighting...
Im confused why you think it isnt a normal mapping tutorial?
