We Plant Trees — Amber Lotus Publishing, an independent carbon-negative US company, has planted more than three quarters of a million trees since 2008. High-quality printing on premium paper stock. Printed on paper sourced from a combination of sustainably managed forests and recycled materials. Features US and Canadian legal holidays, phases of the moon, and important observances of the world's major religions. Fractals are the visual depictions of mathematical equations — the same equations, in fact, that describe natural phenomena such as crystal growth, galaxy formation, plant shapes, and weather patterns. A computer program assigns a color to each point in the image based on the answers to a chosen equation, which then results in cosmic or abstract fractal shapes. Dozens of variables are manipulated in order to create these fascinating images.
