Step-by-Step Instructions

1. Find the Pattern

A Koch curve splits a line into 4 segments. Middle section is a triangle bump.

2. Custom Block

Create a custom block that takes 'length' and 'depth' as inputs.

3. Recursive Drawing

Use the custom block to draw the 4 segments, reducing the depth each time until it reaches 0.
