Precipitation mediumship
This is an incredibly rare and beautiful form of spirit communication which includes images, writings and even signatures that “precipitate” out of the ether onto a surface. Colorful pigments (most often supplied by a medium) are reformed by a spirit and laid down intelligently so that the final product has meaning to the recipient or witness. Neither human hands nor physical writing/drawing/painting tools are involved directly in the process of creating this phenomenon. The most famous example is the incredible portraits by the Bangs Sisters. Read more on Kevin's website.
