Friedrich Fröbel made a series of square, geometric patterns for kindergarten use, calling it “folded forms of beauty”. The intention was for it to be a framework that lends itself easily to explore new patterns. See e.g. Kunihiko Kasahara “Extreme origami”, Sterling, 2002. Taught on the internet by Leyla Torres here: http://www.origamispirit.com/2011/05/windmill-base-variations-video/ <http://www.origamispirit.com/2011/05/windmill-base-variations-video/> in one of her many wonderful descriptions of origami models. > What's important is that the final model ends > up being rectangular, including a square.

Dave Mitchell calls it “Origami Alfresco: sketching without pen or ink”, at least that is the title of his book with many such ones (Watertrade, 2000, 44 pages). He describes it as “drawn without pen and ink, using the contrast between the white and coloured sides of standard origami paper.i” Not all his models, many are irregular. The models are pretty simple and stylised, focusing on folding sequences that are well suited for performing the origami for others. Kunihiko Kasahara calls it “cube art: painting pictures with origami”. “Cube art” was called so because they are made from a windmill-like base with pockets so that the flaps that are otherwise tucked away to form the square of the painting, may be tucked into pockets of four other square paintings to form a cube. Kasahara: “The Art and Wonder of Origami”, Apple, 2004. Square examples on pp 101-121, 64-65, and more. The motives are mainly figurative and includes the zodiacs. In the best Japanese classic origami tradition, some examples have an actually painted eye or such. pp 70-71 displays geometrical triangular “kaleidoscope” patterns and hexagonal “snowflakes”. Mitchell and Kasahara thus agree on calling the technique “drawing”, “sketching”, or “painting” with origami. But not necessarily restricted to a rectangular “canvas”. If you use one-color paper, leaving out the colour change requirement, you get “reliefs” rather than “paintings”. Most tessellations would fall into this category. Tessellations from semitransparent paper is akin to another art form, “glass painting”, in that new patterns/motives may appear when backlighting them. By the way, all of the above books are great reading and folding (the extreme origami even a must-own book).
