Altair Design patterns have a unique property in that they stimulate the visual imagination. Images appear and disappear within the designs depending upon an individual’s imagination and visual logic. The best way to look at the designs is to relax and not get overly fixated on the first image that appears. The original Altair Designs, now shown in Altair Design Pattern Pad #1, were derived from a design that appeared in Calvert’s, “Moorish Remains in Spain,” http://www.archive.org/stream/moorishremainsin00calvrich. Dr. Ensor Holiday discovered a design in the Calvert book that attracted his imagination; a design that was unusual in the fact that it was based on close packing circles and that the circles generated “almost” regular polygons of 4, 5, 6, 7, and 8, sides. To see more about the design and its discovery please visit the publisher’s website; Wooden Books (UK) http://www.altairdesign.co.uk/ . I met Ensor sometime after he had started developing design variations based on the Calvert design and our common interest in design systems resulted in our working together to further develop Altair. Other’s working on developing Altair designs at that time were Jamie McCulloch (design variations), Harriet Dell, nee Crossley, (fabric and wallpaper designs), the Kettlewells (silkscreen prints), Mario DeGrossi (variations), and Robert Colville (programming). Note that Pattern Pad # 1 will reprint in June, so is difficult to find at the moment. Price should be about US$9.00.
