^^^ I'm looking but so far I've only located commercial sites... nothing instructional.
EDIT: Here are a couple of sites showing rainbow anodization. all I can find are commercially available products... sorry. The thing I saw years ago involved high voltage electrodes dragged across the surface of titanium sheet metal resulting in some pretty wild colorful shapes with lightening-like spark patterns. But I can't find anything on that process now.
