'The patterns later became the bestselling Altair Designs – coloring books where each design could be perceived in an almost infinite number of ways. Ensor and I worked together for many years. I developed new hi-tech geometries inspired by the Sarghatmish design based on circles and then spheres that change size and position to generate "perceptual" 3D spaces and architectural structures. Altair represents a type of design that literally changes before your eyes. They are designs that conjure images and patterns in the mind's-eye of a user making whatever is "seen" unique. Altair designs, then, are not like other coloring books – there are no fixed images to color and they serve to stimulate the visual imagination.'
