Mathematical sequences also come into play when Gustlin paints figures and approaches the figures from a mathematical and an emotional perspective. For the last several years Gustlin has been working on a series of paintings, both abstract and representational, that are based on the Fibonacci mathematical theories. Fibonacci mathematical calculations create rectangles and shell spirals based on the incrementally increasing numbers. She explores the relationship of Fibonacci numbers and how it intersects with the arts, and every new design. However, when painting emotions are tossed, it allows personal experiences to flow through the paintbrush and directly onto the canvas. This extension beyond mathematics and science is the creative language of art.
