That sounds like a post production stuff with something like after effects (you can probably do it "painterly" with the animation software of your choice) If the shape or movement of the glow is complex, animate the shape with a solid outline to make the glow effect easier to animate.

For a more graphical style, I'm not quite sure what kind of shape language you'd wanna go for.
