Here are a couple of them.
At work, another programmer and I created two little programs that run hidden in memory. One was called IClick, the other MMove. Both were created as
bots for an online game, but the prank potential didn't take long to realize. IClick clicks your mouse every 55 seconds. We created another one along
these lines that clicks the mouse at a certain interval (the other programmer had to shut down his computer to stop it when I ran it remotely on his
computer with a .1 second interval between clicks.) The MMove program would do one of two things. Either it would shake your pointer, moving it
randomly a few pixles in a different direction than you were moving your mouse, or, with a setting enabled, would shift your pointer 100 points up and
100 points to the left when you'd click.
Hehe we got a lot of complaints of bad mice for a few days before someone caught on.
We've also done the desktop screenshot, too.
Another fun one works when you have cubes. Usually at the bottom of the cube is an access panel for your ethernet connection and phone line. We would
take those off, grab two USB extension cords, and switch people's mice. So the person in one cube would be controlling the other person's
Now that I think about it, it would be even better if we could set up remote access so it appears everything you're doing is happening on your
computer, but all of your files are gone.
Then there's the fun little virus pranks. One which would open a window which listed all the contents of the hard drive with the message,
"Deleting..." That one elected a screem or two. Our response was great, too. Along the lines of, "Wow, that's a bummer. Well, we'll be able to
reinstall everything, and since you're supposed to put everything on the fileserver, it's all been backed up, so there's no real problem." The
look on their faces as they tried to figure out how to tell us they didn't back the stuff up on the fileserver was priceless!
There's also a way in Windows to remap keys. This is really great for the hunt and peck typers or those who look at the keyboard instead of the
monitor. Switching m and n or o and e often goes unnoticed a bit longer, too.
Finally, there's the auto correct in Office. If you can access their computer, open Word and change something common, like "the" into something
else. Then, every time they type "the", it'll change to that text. A lot of people get nervous and think they downloaded a virus and are afraid to
say anything. Good times!
Yeah, we get a lot of work done. Really.
