+1  Q: 

How would I create this background effect?

What would you call the effect applied to the backgrounds in the Giygas fight of Earthbound, and the battle backgrounds in Mother 3? This is what I'm talking about.

Now anyone know how I could go about this without using animated images, or using openGL?

Huh? So it's using 3D?

today, yeah it's the most straight forward way of doing it, use opengl or d3d -- the modern way is to do it in a shader
Gregory Pakosz  2010-05-16 09:27:42
What kind of shader would that be called?
William  2010-05-16 09:44:19
@William You can do this using a pixel shader.Here's a link with some examples http://www.facewound.com/tutorials/shader1/

These are also called demo effects. They are used on demoscene events, beside games.
