This Mindware® illusions adult coloring book uses modern design. Modern design was derived from abstract art, which explores the artists interpretation of natural objects. Each of the original illusion patterns in this coloring book brings to life the spirit of modern design by using form and space to produce sensations of movement and light. These maze-like patterns appear to vibrate off the page; through your selection of color, you can choose to create a vibrant 3D world or dreamlike, mesmerizing effects. Designs appear twice, so you can experiment with the patterns. Includes 23 images printed on artist-quality paper. 8 1/2" x 11"
