Some of my working colleagues occasionally forget to lock their PCs even though they're told to, so a while ago I started opening YouTube videos or image galleries of Nicolas Cage on their desktop so that they learn.

One of them is very resistant to it though and left earlier (it's Friday and he will be back at Wednesday) without locking or shutting down his PC.

So this time I flipped his display, set Shia LeBoef as his wallpaper with a dia show also featuring Nicolas Cage, Ryan Gosling and Daniel Radcliffe and set Nicolas Cage's face as his cursor image.
