The portal gun from the Portal franchise may be one of the most iconic video game weapon symbols across all platforms. While the weapon itself isn't dangerous in game, it does have an intricate and interesting design to it.
Redditor Pastlightspeed put together her very own portal gun for a cosplay she was doing. Pastlightspeed was playing Chel from the game and as such needed a portal gun sidearm to complete the set. Contrary to popular belief, these guns are not sold on every street corner so she had to get crafty. Her homemade portal gun is made of cardboard and costed her less than $10 to make. Given the circumstances and the detailed and accurate design to it, this price tag is more than impressive.
