Click flag. See a simple pattern repeating across scales. You can adjust the total number of levels of the fractal snowflake. If you select 0, it just draws a triangle. If you select 1, it interrupts each side of the triangle with a smaller triangle. Then for additional levels, it draws the same pattern at smaller and smaller scales.
This fractal is a classic that looks like a snowflake, but originally called a Koch curve, published in a 1904 paper "On a Continuous Curve Without Tangents" by Helge von Koch. We include this in our subscription box, frozen fractals--see our exercise cutting a Koch snowflake out of paper.
