Entopic graphomania is a surrealist and automatic method of drawing in which dots are made at the sites of impurities in a blank sheet of paper, and lines are then made between the dots; these can be either "curved lines... or straight lines.". Ithell Colquhoun described its results as "the most austere kind of geometric abstraction." It is to be distinguished from "entoptic" methods of drawing or art-making, inspired by entoptic phenomena.
The method was invented by Dolfi Trost, who as the subtitle of his 1945 book ("Vision dans le cristal. Oniromancie obsessionelle. Et neuf graphomanies entopiques") suggests, included nine examples therein. This method of "indecipherable writing" (see below) was supposedly an example of "surautomatism", the controversial theory put forward by Trost and Gherashim Luca in which surrealist methods would be practiced that "went beyond" automatism. In Dialectique de Dialectique they had proposed the further radicalization of surrealist automatism by abandoning images produced by artistic techniques in favour of those "resulting from rigorously applied scientific procedures," allegedly cutting the notion of "artist" out of the process of creating images and replacing it with chance and scientific rigour. However, the question has arisen whether an algorithm should be used to determine in what order to connect the dots to maintain the "automatic" nature of the method.
The method has been compared to the "voronoi mathematical progression".
