All wallpaper images were rendered with POV-Ray, using CGI models of my own construction. There is some discussion of the models elsewhere on this site, covering source material and my interpretation of it. There are several wallpaper collections, which can be accessed by clicking on the thumbnails below. The majority of the wallpapers are 1440x900, but some are 1920x1200.
Wallpapers that feature the Daleks and ships from Star Trek together can be found in the Star Trek Wallpaper collection.
