Just a little tool to generate a text file containing heightmap information, it generates random noise and smoothes it ut afterwards over multiple iterations. It is also able to stack some of these heightmaps to generate a kind of terrain in octaves. It is a relatively inefficient algorithm, PerlinNoise or SimplexNoise are much faster at this. The advantage is that this little algorithm has less possibilities for artifacts to be generated.

The program is written in Java and outputs a .txt-file, which can be nicely rendered into a bitmap after being imported as "text image" into ImageJ.
