Mason has been making artwork for many years, from pen and inks to surrealist-inspired colored pencil works and paintings. Some of his works have been used as the covers to his albums, such as the interior art for the Augury CD by Trance.

As a graphic designer, Mason was responsible for the bulk of the design for the releases from Charnel Music over the years, as well as albums by KK Null and Mandible Chatter, among others. He also has done the design for a variety of magazines and books.
