Need help with electric effect

[draukadirtch]

Someone had told me that someone used an electric effect to make a picture. It had a pretty basic background and had spidery or ripple of other colors going through it. I don't have an example. plz tell me if you have an idea about how its done if you have any ideas to what I'm descibing.
Thank for you time
