After finishing work on "The Matrix" trilogy, the Wachowskis set up a publishing house, Burlyman Entertainment, for which Darrow provided the logo illustration. Burlyman's output consisted of two paperbacks of "The Matrix Comics" collecting the short comic stories from "The Matrix" website, as well as seven issues of Darrow's "Shaolin Cowboy", published between 2005 and 2007, and six issues of "Doc Frankenstein", a Wachowskis-written and Skroce-drawn series originating from a concept developed by Darrow, which he described as "Doc Savage meets "Citizen Kane"".
