 # perlin noise experimentations
 This is a simple project to experiment with perlin noise. The project is written in c++ using X11 for the windowing system.
-There are 5 different way to generate images using perlin noise built-in the project:
+There are 7 different way to generate images using perlin noise built-in the project:
 
  - cloud effects using 2 superposed perlin noise
- - graph representation of perlin noise in 2D
+ - 2 graph representation of perlin noise in 2D
  - marble effect
  - wood effect
  - one effect that I don't know how to describe
+ - procedural landscape
