Do you know the &#8220;secret to their beauty&#8221; that they all share? It&#8217;s a fascinating property: a small part, when magnified, reveals a shape uncannily similar to the whole.<\/p>\n<p>This design rule hidden in nature is called a &#8220;fractal.&#8221; And today, we&#8217;re going on an adventure to create these mysterious fractal shapes using the programming tool, &#8220;Scratch&#8221;! It&#8217;s like being a magician, combining simple commands to bring a complex and beautiful world to life. It&#8217;s truly a blast!<\/p>\n<h2>First, the finished product!

The magic spells needed to draw this shape are just two. &#8220;Create Block (the magic to create your own commands)&#8221; and &#8220;Recursion (the magic to call yourself).&#8221; So, let&#8217;s unlock the secrets of this magic together!<\/p>\n<p>Step 1: The Basic Spell &#8211; &#8220;Triangle, Appear!&#8221;<\/p>\n<p>First, we&#8217;ll create the program to draw an equilateral triangle, which is the basis for everything.

The program keeps calling itself, and the cat draws endlessly without stopping! It&#8217;s a runaway program! Yes, you need to tell this magic when it&#8217;s time to stop.<\/p>\n<p>Step 3: Control the Magic and Complete the Art!<\/p>\n<p>To stop the runaway magic, we&#8217;ll add a stopping condition: &#8220;If the side length is greater than 10, continue the process.
