It happens to all of us that work in an office with more than one person. Someone runs out of pens or paperclips, and suddenly your desk is a free-for-all buffet of office supplies. While it’s not a huge deal (other than being a bit annoying), it is hilarious to catch someone in the act.

The Portal 2 Sentry Turret USB Desk Defender is a motion detecting turret that will open and alert whoever is within ear shot that someone has approached your desk. It stands at about 7.5” tall, and will spout off phrases like “Target acquired”, “I see you”, and “Activated”, which will surely give anyone a good scare if they’re not expecting it. If this happens to be knocked over, it will vibrate, and give off a new line of saying like “Critical error”, “I don’t hate you”, and “Hey, hey, hey”. If you ignore it for 30 seconds, then it will ask if you’re still around. This little collectible will cost around $30, and is plug-and-play.
