There are lots of schools and businesses who are getting sick and damn tired of projectors walking off on their own, so Hitachi offers the ED-X10 projector that looks like it's wearing a jailhouse jumpsuit.
Not only is it colored a garish signal orange, it has a host of security features built in to keep that projector from the clutches of sticky fingers. It has a transition detector that locks it up if it's moved, and the only way to unlock it is by using a PIN number. If that's not enough, it has a steel security bar that lets you literally lock the thing down. Good luck jacking this one, thieves.
