Used CraterSaver for Windows?
Developer’s Description
By Bret Logan
You'll understand how large-scale features we see on the moon could be achieved by incremental small-scale modification. A crater-simulation program implemented as a screensaver, that slowly turns a flat piece of ground in to a scarred, Mercurial landscape.
The idea was basically to try and understand how large-scale features we see on the moon, could be achieved by incremental small-scale modification. It turned out that creating craters is the easy-part (all craters are circular, small ones have parabolic depths, medium ones spherical depths, huge ones are have mostly flat bottoms with a peak in the middle). This version is the first release on CNET Download.com.
