Each Harmonogram was coded by me from scratch with unique mathematical parameters to create intricate, harmonic shapes reminiscent of those drawn by pendulums. Thus, each of these complex shapes have been generated with precise geometric measurements and mathematical accuracy  \u003cp\u003e\u003c\/p\u003eThe book features both symmetric and asymmetric shapes constructed in multiple layers. The layers can be various combinations of ellipses, spirals, figure-of-eights and other Lissajous figures. Superimposing these layers creates interesting complex waves and three dimensional shapes. Traditionally, harmonograms are drawn with different colored lines. However, I am sure you will find your own hidden images within the harmonograms as you color and create patterns within (or even over) these lines  \u003cp\u003e\u003c\/p\u003eThe harmonograms chosen for coloring have different complexity of their patterns and thus some may be easier to color whereas other are more challenging. The harmonograms are ideal to combine with color palettes in repeating blocks of color for maximum challenge and aesthetic impact  Additionally, there is space around each harmonogram for you to draw, doodle and tangle your own contributions  \u003cp\u003e\u003c\/p\u003eI hope this provides you with an escape from the business of the world outside by challenging your creative skills\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Tanzelle Oberholster\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 8566420683\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798566420684\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 11\/21\/2020\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 110\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.60lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.00h x 8.50w x 0.23d","brand":"Tanzelle Oberholster","offers":[{"title":"Paperback","offer_id":45897101738239,"sku":"9798566420684","price":8.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_7bf97db8-bde5-45bc-b2ec-dbd9fe1f64cc.jpg?v=1721373161","url":"https:\/\/www.whiterainbookhouse.com\/products\/harmonogram-pendulums-challenge-tanzelle-oberholster-9798566420684","provider":"WR Book House","version":"1.0","type":"link"}
