Imagine a terrain height field, where white is the highest height and black is the lowest height. We'll stick to 2d for ease of visualization. We can generate an interesting organic-looking height field like this with noise:

Not bad, but not good either. We can make it look MORE like terrain by mimicking the effects of erosion. If you imagine material sliding down steep slopes to re-distribute some of the height, it might look more like this:

Fork this base code and replicate (to the best of your ability) this erosion effect. More detailed instructions inside!

Add some coloring to give the terrain some personality.
