He-he.
On my first cellphone I had "Don't Panic" as my welcome message. I am among the lucky owners of "The Illustrated Hitch Hiker's Guide to the Galaxy" (1994), and haven't looked at it for years until now, so thanks for reminding me.
I found a very nice blog about hand crafting height maps some time ago. That's really where I got the idea. But unfortunately it seems to be deleted.
My handcrafting is mostly limited to small objects, like hills, paths, roads, ponds, lawns, trenches and so on - things that are next to impossible to make just by manipulating auto-generated procedurals.
Making very small variations in height is of course dependent upon applying a general height reduction after the model is created.
