A bit about the Sierpinski Triangle: The Sierpinski Triangle is a fractal named after the Polish mathematician Wacław Sierpiński (1882-1969). Its overall shape is typically that of an equilateral triangle and it can be subdivided recursively into smaller equilateral triangles. The Sierpinski Triangle is a basic example of self-similar sets as its pattern is reproducible at any magnification or reduction.
