Ranbu is a year-and-a-half-long project that consists of over 80 pieces named after a Japanese pop single "乱舞のメロディ(Ranbu No Merodi)" - Melody of the Wild Dance by SID. This body of work displays Mac's whimsical use of color, blurring the lines between the worlds of fine art and design with their rawness, chaos, and freedom, and the world of design with its structures, principles, and utility. Mac developed this abstract and modern collection with her diverse expertise. The series has been called "paintings that paint themselves" and "camouflaged painting" since each acrylic painting on laser-cut plywood was made without the use of a paintbrush with the final product looks like a Victorian piece of ceramic on uniform square canvases. Over the years, Ranbu's pieces received many awards and were exhibited at art shows, and institutional art museums across the U.S., Italy, Ireland, South Korea, and more.
