Phillips' best known work is "A Humument: A Treated Victorian Novel originally by W.H. Mallock". One day, Phillips went to a bookseller's with the express intention of buying a cheap book to use as the basis of an art project. He randomly purchased a novel called "A Human Document" by Victorian author William Hurrell Mallock, and began a long project of creating art from its pages. He paints, collages or draws over the pages, leaving some of the text peeking through in serpentine bubble shapes, creating a "found" text with its own story, different from the original. Characters from Mallock's novel appear in the new story, but the protagonist is a new character named "Bill Toge", whose surname can only appear on pages which originally contained words like "together" or "altogether". Toge's story is a meditation on unrequited love and the struggle to create and appreciate art.
