I was impressed by this effort: a life-size paper model of Samus Aran's armor! Using a 3D model from Metroid Prime 2 video game, Flickr member IAmThatOneGuy built the 6'-10" (2.1 meters) tall model over the course of several months. Unfortunately, there is no download for this one, but I had to share because of the "coolness" factor. ^^ More photos of the build may be seen
here.
