We’ve seen some nifty Portal turrets in real life before, but not one that actually shoots. A Penn State University student created this currently frameless turret for his Advanced Mechatronics class’ final project. The turret, like in the game, tracks its victims via an IP webcam, as well as shoots at them, though luckily for said victims it only shoots Nerf bullets. He’s working on a frame so the thing looks more like the iconic white turret we’ve all come to love and fear, and yes, the turret also talks in that sing-songy, haunting voice. Check out a video of the thing in action after the break.
