Koch snowflake

A Koch Snowflake is a cool pattern made up of triangles. You can draw it by starting with an equilateral triangle (a triangle with all three sides being the same length), and then repeating a certain pattern on each side of the triangle. The pattern starts by drawing a line from the midpoint of one of the sides of the triangle towards the opposite corner. That line then has a "V" shape drawn in the middle of it, extending to both sides. Finally, two more lines are drawn from the corners of the "V" to the opposite corner of the triangle, creating four smaller triangles. That pattern is then repeated on each side of the starting triangle, and each time the pattern is repeated the triangles get smaller. Eventually the snowflake is made up of very small triangles!
