Rafael Araujo is an architect and illustrator from Caracas, Venezuela. For over 40 years he has been drawing beautiful illustrations of nature, entirely by hand. At an old drafting table he adeptly renders the mathematical brilliance of nature with just a pencil, compass, ruler and protractor. Rafael applies the Golden Ratio to his geometric formulas and leaves the construction lines intact to highlight this natural mathematical framework. Rafael has been featured on CNN and in publications such as Wired, Fast Company, Mashable, My Modern Met, and WWF's magazine. His illustrations have been shown at Stanford University and in major exhibitions and galleries around the world. More than 30,000 people follow his work at fb.com/rafaelaraujoart.
