I think it was something like you could type some numbers and the computer would generate a mountain scenery with sky, greens and lakes.
It ran fine on A500. Took a little while to generate the picture.
I think it was freeware.
Sounds like "SceneGenerator" which was on AUI Superdisk No.42, September 1994 issue of Amiga User International. Also had Model4D on it amongst other stuff. Quite a nice disk. All AUI disks were good come to think of it.
