Comment Better example (Score 2) 91
While definitely cool project, I think there are better examples out there. http://www.youtube.com/watch?v=6QcfZGDvHU8#t=16 also shows an auto tracking turret with portal voices. However in this case the tracking seems quick enough to be useful, and it actually hurts people. Add some white plastic, and you're pretty close to the "real" deal.
