Dougal McKenzie links to an interesting essay about artist Henry Darger, Realms of the Unreal by Stephen Prokopoff. The essays title refers to Darger's own "picaresque tale in 12 massive volumes composed of some 19,000 pages … entitled The Story of the Vivian Girls, in what is Known as the Realms of the Unreal, of the Glandeco-Angelinian War Storm, Caused by the Child Slave Rebellion… It took more than eleven years to write it in longhand."  Darger created "several hundred watercolor paintings" along with the written manuscript.  Click through to the essay from McKenzie's post.
