President of ADROIT Origami, Travis Nolan, was commissioned this summer by BenBella Books to design and fold an origami bull from a $100 bill for the cover of Wealth Made Easy: Millionaires and Billionaires Help You Crack the Code of Abundance by Dr. Greg Reid. Travis designed the bull using a technique called "22.5 degree design" in which the angles of the intersection of all (or most) creases in the crease pattern of the model are restricted to multiples of 22.5 degree angles. This is a more difficult way to design, but it usually yields a very good result, if done properly. The bull was folded from a single $100 bill, without cuts or glue.
Wealth Made Easy will come out in April of 2019.
