Paper sculpture is hardly a new form of art, but Marco Ercoli is bringing it into a whole new level with his inclusion of using Post-It notes as his primary art tool.
Just check out this Samurai sword. It's a 1:1 ratio in size and looks like it could give you one hell of a paper cut. That's just for starters though.
Ercoli has managed to sculpt out other weapons like a grenade, a revolver, and a car--all life-size and proportion. If this sword takes 4,000, I'm trying to figure out how many the car takes. Even the wheels are constructed from the handy office supply!
