Dettmer's current work involves the appropriation and alteration of media to transform the physical form and/or to selectively remove and reveal content to create new works of fine art. Dettmer explains: "Old books, records, tapes, maps, and other media frequently fall into a realm that too much of today's art occupies. Their intended role has decreased or deceased and they often exist simply as symbols of the ideas they represent rather than true conveyors of content. … When an object's intended function is fleeting, the necessity for a new approach to its form and content arises."
