Sierpiński curve

A Sierpinski curve is a shape made up of repeating triangles. It was invented by Polish mathematician Wacław Sierpiński. To draw the shape, you start with a large triangle and then draw three smaller triangles inside it in the corners. Those three new triangles make up a new shape, and this process is repeated over and over again with each new triangle. It looks like a triangle made of triangles, and each time you draw one new triangle, the pattern looks more and more detailed.
