In 1972, the American biologist and father of the crytozoolgy Ivan T. Sanderson, publishes « the Twelve Devil’s Graveyards Around the World », in which he develops a theory locating twelve specific geographical zones around the world that he named « vil vortex ». These zones, positioned according to a precise geometrical pattern, are, according to the author, the theater of mysterious disappearances and strange phenomena. These informations are used as starting point by Maxime Bondu to reinvents a possible theorem allowing to draw zones on a planisphere as described and positioned by Sanderson. Once drawn on a map, zones are carefully extruded, leaving empty spaces, and folded in a random way to create geographical correspondences and holes which appears then as the representation of possible passages. The forms obtained, placed under a frame of the original size of the map, also formalize the space left by the folding and calls back one of the big theories of the contemporary cosmology; the universe could be smaller than planned and would be similar to a ball of crumpled paper.
