Perlin Builder

Generates 2d terrain and heightmap jpeg using Perlin noise.

Probably a good place to look in for anyone starting with Nannou.

I wrote this project to learn about Nannou and Rust. Constructive criticism is more than welcome.

Controls

'O' && ( '+' || '-' ) : Adjust the octaves.
'Z' && ( '+' || '-' ) : Zoom in and out
'W' && ( '+' || '-' ) - 'H' && ( '+' || '-' ) : Adjust the image dimensions.
'S' Save the image to the current directory.
'R' Get a new random seed.
'M' Toggle between the two modes, colored terrain or heightmap.

Some examples
