A mathematical rose curve, controlled by 2 variables, set by data from the block. Creators control the size and thickness of each rose, along with border thickness and opacity. Change the color of the rose or border, and determine the look of buds and blooms. Oh yeah, watch out for roses that bud, and even more rare, roses that have bloomed. Search for integer roses and the illusive upside down roses. The Maurer rose geometric logic was created by Peter M. Maurer in 1987.
