When asked to plan a generative moving landscape, I immediately thought of the game, Journey. This is a visually stunning, emotionally oriented game where you, a cloaked wanderer fly through a landscape of sand dunes, old buildings, ruins and caves.
I tried to refer to the color scheme and the my favorite structures, the posts, in this sketch. I used noise functions to render the scenery. I used a random function for the color of the posts to create a dust-wind effect.
