Uses a chaos game to generate a Sierpiński triangle. The method is as follows:
- Start by drawing 3 points to form the vertices of an equilateral triangle.
- Draw a point in the center of the triangle (or anywhere).
- Randomly select one of the three vertices.
- Draw another point halfway between the center point (the one that is not one of the triangle's vertices) and the selected vertex.
- Repeat steps 3 and 4, but with the newly drawn point and another randomly selected vertex.
- With sufficient iterations, a recognizable pattern should emerge.
