This V-12 four-stroke engine was constructed entirely out of paper -- 1,978 pieces to be exact. Weighing in at a little over 3 pounds, it certainly ranks as one of the lightest V-12s around. It also ranks as the one most likely to cause a serious paper cut. Perhaps the most amazing part of the whole thing is that it works -- producing a 13.5RPM crankshaft speed via 2 AA batteries. Over two years in the making it truly is a work of art. Well, it was until I filled it with gas and produced a spark. Then it was truly a fireball.
Several more pictures and a video of the action after the jump.
