How 'bout having some fun experimenting with plating and other cool coatings and finishes? Try looking at the Eastwood home plating and coating kits. Lots of options like blackening and other electro-finishes. The kits are easy to use, and there are lots if kits that mimic dangerous-to-do-yourself finishes like chrome and nickel.
Caswell does lots as well, including bluing.
One last thought. I have recently discovered "crinkle finish" black in a spray bomb. Looks great and works well with a thoroughly prepared surface. Probably not great on tiny pieces, but never tried.
