Yes to what Ben said. First of all, let me ask if the attached graphic is the type of thing you had in mind.
You can display the static image in an image indicator gadget for the off state, and then for on, display the moving graphic.
If this is what you are looking for, let me know the specific animated graphic you have in mind. I’ll post it here, and soon I’ll create a dedicate resource page for these.
