What screensaver for Windows can display a console window, and be used to run a custom console application?
For example, a screensaver that could be configured with the command "ping -t 10.0.0.1". When activated, it blanks the screen and displays a continuous ping to a host. Then when the mouse moves, it terminates the "ping" process.
(That was an example; I'm looking for a general-purpose screensaver that can run any console application.)
Does such a thing exist?
