What is "weathercraft"

Weathercraft is a 2010 graphic novel by American cartoonist Jim Woodring, featuring his best-known characters Frank, Manhog and Whim. While Frank stars in most of Woodring's stories set in the fictional universe of the Unifactor, this book stars Manhog, with Frank making only a brief appearance. Manhog, after trials and tribulations, sets out on a transformative journey, returning to face off against the devilish Whim, who has enslaved and transformed his friends. Like all other stories set in the Unifactor, Weathercraft unfolds entirely in pictures, with no dialogue balloons or captions. Weathercraft was Woodring's first book-length work.
