以摺為主題，探討可動的摺紙物件：「東西南北」。由它的摺痕胚騰出發，衍生出3種單元：風車狀平面、重要中心及改變摺痕定義得到的新摺痕胚騰。接著，以3種單元加上原始物件，透過有次序的單元增加去觀察形態的變化。
　　單元以相同次序組織單元，卻衍生出不同的形態，而所有形體皆由同一元素：45∘/45∘/90∘等腰直角三角形。以不同的元素量與元素位置及元素間角度的變化，所構成的「同素異形體（Allotropes）」，並以元素的角度關係將方法命名為：1.1.2-L。
　　方法1.1.2-L內含四個系列，以系列為單位發展四個設計，四個設計有各自的運動機制，在運動過程中形態也呈現出不同的樣貌。

　Origami as topic, investigate the action origami object “Fortune teller”. From the crease pattern derived 3 forms: kite, main center and the new crease pattern of change the crease definition, deemed 3 different units. Next, the 3 units and original object began forming in the same sequence and observe the morphological changes.
　Units are organized in the same sequence instead derived distinct forms, and all the forms constituted by same element: isosceles right triangle. Namely same elements different quantity and different structure, obtain different form, the concept like Allotropes, and named the method: 1.1.2-L from the degree of the element.
1.1.2-L has 4 series in, each series developing one design; each design has its own moving mechanism, during the movement form showed the morphological change.
