    Same concept of XY displacement, but X displacement needs to be inverted when a surface is aligned along Z to give the illusion of the light comming from the observer. Completely unrealistic lighting tricks.

    I don't feel like I can make any more dweets with so many good ones like this roaming around.

    Getting on the bump train with a different method. This one displaces X and Y in proportion to distance from light source, which creates pixel gaps on one side (specular highlights), and overlapping pixels on the opposite (becoming shadows).
