Use Preview's full screen mode for a simple prank Apps
If you use this older hint backwards, you can play a pretty funny practical joke on people. When someone is away from their desk, take a screenshot (Command-Shift-3) and open it in Preview. In Preview's View menu, select Full Screen, then click the mouse somewhere on the image (to get rid of the warning message about full-screen mode). Presto, your co-worker now has a seemingly non-working machine...

The moral of this story is always hit escape if it looks like your computer is frozen, and you have co-workers or room mates who think they're funny.

[robg adds: Actually, the real moral of the story is to always lock your machine when you leave your desk! As noted above, hitting Escape will exit full-screen mode, or a simple command-tab will show that the Mac is actually fine. The dock, however, will be of no help, since it's (somehow) disabled in Preview's full screen mode. If the victim-to-be has multiple monitors, this trick is quite a bit more difficult to pull off ... exactly how is left as an exercise for the reader. :)]

Athough the dock is disabled, Expose still works. Still it's a cool, quick trick.

surprisingly, you can switch to another user if you click your mouse in the upper most right corner of your screen. The date and applescript menu items seem accessible as well.

Even meaner:

1) Download/Install Developer Tools
2) Write a quick program in C/OpenGL which disables the escape key (or all keys).
3) Do said trick above
4) Put C program in front

You could also make the program move the mouse back to a random spot on the screen after every few seconds, just to throw them off.

Even more fun, rotate the screenshot 180 degrees so it's upside down!

Turn the second monitor off or unplug it. That will reenforce that there is a really a problem! :-)

Hida all programs except for the Finder (keep a few Finder windows open), take screenshot. Change the Desktop background to the screen shot. Enjoy when the (l)user tries to close windows or click icons that really does not exist.

Yet another prank...
Authored by: xone on Aug 02, '04 07:15:21PM

On the topic of pranks to play on the unsuspecting and clueless, here is one a friend and I like to play on people.

Simply enable the universal access zooming with apple + option + 8, then zoom in as far as you can using apple + option + =.

Most people are unaware of this and can spend ages working out what is going on, let alone how to fix it. Tee hee hee :)

And for screen savers?
Authored by: bsdrawkcab on Aug 04, '04 02:28:09PM

Is there any way to get such a screen shot to render well as a screen saver?

Also try hitting Control + Option + Command + 8. It will change the accessibility option to inverted colors. Makes it look as if the monitor is broken. I think there was a previous hint about this on April fools day one year.

When Microsoft asks you, "Where do you want to go today?" tell them "Apple."
