A **Sierpinski triangle** or **Sierpinski triangle gasket** is a fractal resulting from doing the following:^{[1]}

- Start with an equilateral triangle.
- Remove center part.
- Do the same for the three largest equilateral triangles left in this one.

If this is done, the first few steps will look like this:

If this is done an infinite number of times, its area will be 0.

They can also be 3D:
