What better way to protect your monitor's phosphor than by smashing
rocks into it at dozens of kilometres per second? The
Craters Screen Saver
simulates cratering of initially flat terrain, obeying the same
power-law relating crater size to number observed on airless solar
system bodies. New version 3.0 is compatible with dual screen
configurations on Windows XP and saves preferences in the registry
individually for each user. This is a minimalist screen saver
originally released in 1994 which
appeared in the November 2000
issue of Sky & Telescope magazine.
Retro-computing enthusiasts may
download the original version for Windows 3.1 which runs fine on a 20
Mhz 80386 and will probably work on a PC/AT with an EGA.
