Shaders are used extensively in modern video games to achieve a wide variety of effects. Some shader effects are very obvious, like the Sumi-e watercolor style applied to kami. Others are so subtle and routine that we often overlook them which means, in many ways, that they are doing their job well.

consider a game that you have played recently with a really well-done shader effect. This may take some research on your part in order to determine that a shader was in fact used and that the effects are not due to some other process. venture a guess as to how the effect was accomplished. Be sure to identify whether or not the effect utilized a 2D shader or a 3D shader.
