Lego Sentry Gun

While Lego might not approve of making Lego guns, you really can't stop Lego fans from making anything they want from Lego - including guns. In this case, it's an automated Sentry Gun, inspired by the computer game Team Fortress 2. This is definately no easy feat to make!

You can see more shots of it here. Made by Steve Barker. You can see his other creations here.
