A couple of space colony summer studies were conducted at NASA Ames in the 1970s. Colonies housing about 10,000 people were designed. A number of artistic renderings of the concepts were made. These have been converted to jpegs and are available as thumbnails, quarter page, full screen and publication quality images. Illustrations by Don Davis.
