Why spend hundreds, if not thousands, of dollars on expensive prop replicas if you have the skill to make them yourself? Flickr user CitizenSnip has those skills, obviously. His A3-21 Plasma Rifle replica looks like it fell out of the Fallout 3 video game and into the real world.
No amount of glue, paint, and popsicle sticks would give me the same results. Check out his Flickr page for over 60 photos of the amazing model, from conception to completion. If the real world ever gets to be anything like Fallout 3, I'm calling CitizenSnip.
