London-based Bare Conductive Ltd. makes electrically conductive paint called Bare Paint. The substance allows the painting of "liquid wiring" on any surface. Except for skin, you can apply its paint on walls and assorted surfaces to conduct electricity. "Bare Paint" began as a project by the inventors, then students, at the Royal College of Art. Despite all the jokes about Wikipedia as a questionable knowledge crutch, the inventors credit Wikipedia as having helped them to learn what they had to know about working with conductive materials to get something going. In 2011 the RCA graduates were able to introduce Bare Paint.
