I used to do the same thing to a few people back in the day. Linux distros used to ship with the X listening port just conveniently wide open and the config set to allow input from any other device on the LAN. I’d start with only one xeyes, and then they’d close it. I’d do it a few more times until they got irritated with me, and then I’d push it further by putting xeyes into a bash loop to open dozens at a time.
