Came accross this brilliant abstract comics page by Ibn al Rabin, real name Mathieu Baillif, from Genève. Apparently this had its first life as a photocopied fanzine. The original page (in real size) you can find here. I have no idea if this is in any way influenced by George Spencer Brown‘s calculus of distinctions; but Andrei Molotiu informed me that Baillif is a mathematician, so that is a real possibillity. This calculus is sometimes explained using rectangles, below an example taken from ‘Form Dynamics‘. The whole existence of abstract comics came to my attention through a post by crystalpunk.
