In college, during the time I worked at the campus library in Stack Maintenance, on some days I also worked in the library computer lab. A joke we played on one friend was to take a screenshot of the regular computer desktop and make that the startup screen.

And the background screen.

And then use ResEdit to allow us to hide all the rest of the regular UI elements unless you typed the magic keyboard combination to un-hide them.

But that was a joke we played on a single friend. We knew that our friend could take a joke, and he wouldn't try to take revenge against us, or anything. No way we would do that on the general public.
