Restored: Littoral
Technically, the project entry is for Kevin Fishburne’s short-lived Ultima 5 – TES3 Mod, which currently resides in the Aiera Orphanage. However, the released download associated therewith is actually Littoral, his powerful terrain heightmap generation software.
He is actually still working on the software; a heavily updated version is assisting him in creating his new project, Sanctimonia. Thus far, he hasn’t released that version to the public, but you can download the older version at his old project’s entry.
I thought I’d released it, but may have forgotten. I reposted it here:

Incomplete but effective.
