Paper is useful for a lot of things. You can write the great American novel on it, you can wrap your fragile belongings before you move, or you can do what Taras Lesko did and build a massive (and very convincing) fighting robot.
Lesko constructed this RX-178 Gundam as a demonstration of his mastery of papercraft, a phenomenon that seems to just keep getting cooler. It took 720 sheets, but those sheets were cut, folded and warped into 1,250 parts. Lesko doesn't mention how long it took, but there's no doubt the effort is impressive.
All the paper is held up by a very simple 12-piece support frame, and though it looks sturdy and ready to kill something, the whole Gundam only weighs about 10 pounds. Lesko built a 4-foot version of this beast back in 2010, but this time he decided that just wasn't enough, and the results are awesome.
Now if we can only get someone to replicate that full-scale Gundam the Japanese built last year ...
