Recursion is the process of repeating items in a self-similar way. Recursion can be implemented in Scratch by making a block that uses it self. This can be used to create fractals. A fractal is pattern that produces a picture, which can be zoomed into infinity and will still produce the same picture. Some common examples of fractals are The Mandelbrot, The Sierpinski Triangle, and The Koch Snowflake.
Creating the Koch Curve
The Koch Curve is a fractal that can be created relatively easily in Scratch. The Koch Curve is part of a larger fractal, the Koch Snowflake.
