A standard CPK model, colored by element, against a stone background.The flat base-pairs are stacked in the center of the strand, perpendicular to the view, and the backbone makes a right-handed spiral around the central, vertical axis.
This is a plain CPK model, but with a world map texture-mapped onto the surface.It was riginally a demo for one of my commercial clients. They decided they wanted something a little different, so I put it up here
