Due to office shenanigans, I try to leave my computer locked when I step away. Sometimes I forget and hilarity ensues.
What I'd like, though, is a way to detect when attempted shenanigans occur. That is, I'd like my screensaver to simply look like an unlocked computer but change in some way when it's disturbed. It doesn't need to be overly convincing--just a simple freeze until touched is fine.
Anything like that out there?
