That's exactly how things turned out for Flickr user OmegaStation. Using the Automator application that ships with Mac OS X 10.4 Tiger, he had written a small workflow script for his MacBook that instructs the built-in iSight cam to snap an image every time the notebook wakes up from sleep, then upload those images to a Flickr account.
Having forgotten about the script, the user at some point needed repairs done to his MacBook and shipped the notebook off to Apple. It was to his surprise when images began appearing on his Flickr account — apparently from inside one of Apple's authorized repair facilities, Flextronics International in Tennessee.
Although OmegaStation has since removed or edited many of the photos due to privacy concerns (the cam snapped the faces of several Apple technicians), a few remain available:
