The motion activated portal 2 sentry turret is an absolute delight for anyone who has played the game. On the surface, it looks like a fairly high quality reproduction of a turret from Portal 2. That's also part of the charm. Because the real fun of the turret comes from the element of surprise.
When the turret's USB cable is plugged in, it will enter a guard mode. This is also quite similar to how the turrets behave in the game. In the game a turret will detect the player's motion, and in real life it will detect the motion of friends, family or coworkers who stumble into it's path.
When the turret detects motion it will yell out one of the many random phrases used in the game. It might get a grin from someone who's not familiar with the game. But anyone who is familiar with it will get a huge kick out of it. It's not that uncommon for people to deliberately rush through areas of an office where people have them on their desks. This can make it a great, if somewhat disruptive, gift for offices that have a lot of gamers. And of course it's almost a prerequisite for the dark hallways of data centers.
Though the ultimate office game involves using the turrets alongside soft dart guns. Because not only will the turret detect motion, it even has the appropriate response to being shot. If a turret is knocked over it'll issue a specific statement, such as "I don't hate you".
Amusingly, the turret even shows the same response to being left alone as one would find in the game. If the turret isn't played with for a while it will issue forth a mournful "Are you still there". Thankfully this real world version won't continue to repeat that. Otherwise nobody would ever allow it into an office.
If you are a Portal fan, you will get a kick out of this awesome device. This Portal 2 Sentry Turret motion detecting device is a fun way to know if anyone is invading your space, whether it be your bedroom or your office space. It comes programmed with more than 10 sayings. You will enjoy having this little guy around!
