Automated landscape 

This project relates to a painting I made by algorithm when I was in school in 1971.

The steps are:
1. Draw a steep zig-zag line to make a mountain range
2. Draw a less steep zig-zag line to make a range of foothills
3. Draw a smoother zig-zag line to make rolling countryside
4. Extend the lines thinly to divide the space into geometric sections
5. Paint the sections using sky, mountain, hill and field colours
