Where I work we have a CNC machine (among many) that -must- be watched or it will go into alarm. Stand there and watch it and it'll run all day. Walk away from it and it goes into alarm. It's really old, made in about 1994 or about 15 years old. We put the new guys on it so we can weird them out :) We tell them that's it's alive, hit by lightning once, and that it hasn't got any eyes so it's like a little kid in the dark.
The reality of it is that it's probably got some bad electronics in it somewhere that are acting sorta like a proximity switch.
It does kind of weird you out :)
