His visual art takes a variety of forms, including painting, photography, drawing, video and installation. He has shown his work internationally, with solo shows at the Stellan Holm Gallery in New York, the Laura Bartlett Gallery in London, and Lemon Sky Projects in Los Angeles and Miami.
In 2005 two of Moser's large-scale Untitled Backdrop paintings were purchased by the collector Charles Saatchi, selected for inclusion in one of his Triumph of Painting exhibitions.[1]
He is also a writer, primarily of screenplays. Moser taught screenwriting for several years at CalArts, and helped found the literary magazine Black Clock. He was senior editor of this publication for four years, and now serves as editor-at-large.
