<a href="http://www.theguardian.com/books/2016/jan/27/scientists-reveal-multifractal-structure-of-finnegans-wake-james-joyce">Scientists find evidence of mathematical structures in classic books. <small>[The Guardian]</small></a> <a href="https://en.wikipedia.org/wiki/James_Joyce">James Joyce</a>'s <a href="https://en.wikipedia.org/wiki/Finnegans_Wake">Finnegans Wake</a> has been described as many things, from a masterpiece to unreadable nonsense. But it is also, according to scientists at <a href="http://www.ifj.edu.pl/?lang=en">the Institute of Nuclear Physics in Poland</a>, almost indistinguishable in its structure from a purely mathematical <a href="http://imagej.nih.gov/ij/plugins/fraclac/FLHelp/Multifractals.htm">multifractal</a>. <blockquote>"The absolute record in terms of multifractality turned out to be Finnegans Wake by James Joyce. The results of our analysis of this text are virtually indistinguishable from ideal, purely mathematical multifractals," said Professor Stanisław Drożdż, another author of the paper, which has just been published in the computer science journal Information Sciences.

<a href="http://vimeo.com/channels/bkcfilms/98290488">Trio for Three Angles</a> (1968) is one of many beautiful acclaimed visually-oriented short films with music by <a href="http://www.afana.org/cornwell.htm">mathematical filmmakers Bruce and Katharine Cornwell</a>, some animated by hand and some using early digital technology. It inspired three sequels: <a href="http://vimeo.com/channels/bkcfilms/98290491">Similar Triangles</a> (1975), <a href="http://vimeo.com/channels/bkcfilms/98290485">Congruent Triangles</a> (1976), and <a href="http://vimeo.com/channels/bkcfilms/98297985">Journey to the Center of a Triangle</a> (1978) (<a href="http://www.metafilter.com/94416/Quasihypnotic-mathematical-construct">previously</a>). <a href="http://vimeo.com/channels/bkcfilms">Other extant films by the couple</a>, recently generously released by their sons Eric and Scott Cornwell under a Creative Commons license "to encourage artists, educators, and others to give these images new life", are:
<ul><li><a href="http://vimeo.com/channels/bkcfilms/98290486">The Seven Bridges of Königsberg</a> (1958), on Leonard Euler's famous solution to the topological problem</li>

Almost everything about <a href="http://books.google.com/books?id=5d9hHvD-T7gC&dq=%22What%20Happened%20at%20Cambridge%20IV%22&q=%22What%20Happened%20at%20Cambridge%20IV%22#v=onepage&q=%22What%20Happened%20at%20Cambridge%20IV%22&f=false">the incident at the Cambridge IV supercomputer facility</a> where Berryman conducted his last experiments has been suppressed and classified as highly undesirable knowledge. It's generally believed that Berryman and most of the facility staff died. Subsequently, copies of basilisk B-1 leaked out. This image is famously known as <a href="http://data.tumblr.com/13741903_500.jpg">the Parrot</a> for its shape when blurred enough to allow safe viewing. B-1 remains the favorite choice of <a href="http://www.infinityplus.co.uk/stories/blit.htm">urban terrorists who use aerosols and stencils</a> to spray basilisk images on walls by night. <a href="http://www.readability.com/read?url=http://www.greenfield.narod.ru/langford_eng/differ_kind.html">But others were at work on Berryman's speculations...</a></tt> (The quoted FAQ section was too pithy a summary to pass up, but it did constrain the order I could put the links in. So if you don't have time to read everything, I'll just note that the last and second-to-last links are IMHO the best content in the post, in that order.)
