Each of the original circular patterns in this Mindware® coloring book for adults brings to life the spirit of modern design by using form and space to produce sensations of movement and light. These spherical patterns appear to twist, whirl and gyrate off the page; through your selection of color, you can choose to create a vibrant 3-D world or experience the calmer effects of circular motion. Designs appear twice, so you can experiment with the patterns. Includes 23 images printed on artist-quality paper. 8 1/2" x 11"
