The document provides instructions for modeling ferns using the GIMP software. Students are tasked with creating at least three realistic ferns digitally that display biological characteristics of real ferns. The tutorial involves three main steps: 1) carefully transforming the form and size of triangles, 2) changing colors as desired, and 3) using fractals and iterated function systems to generate the fern patterns. Examples of different plants and ferns created with GIMP are also included, along with a link to more information on generating fractals in GIMP.

4. Ferns with GIMP
The task:
Model three ferns or more with GIMP.
Include in your common report a description how this
works and photos of relaistic ferns with biological
characteristics that are similiar to your creations.
