Amazing Origami

"Built by a self-employed Montreal man named Yee, the Origami V-12 is a paper engine that pumps just like real engines (with the help of electrical wires, a resistor, a motor and a battery holder). It looks complicated because it is: One V-12 engine consists of 195 sheets of fine-printed patterns. From those sets, 1,978 pieces are used in total. And it only weighs 3.2 lbs when finished. This makes your 1,000-piece puzzle look like a piece of cake.

But if you have the intestinal fortitude to go through with it, the build comes together rather beautifully: The engine representations include a compound crankshaft (running at 13.5 rpm), cooling fan, 12 rods, 12 pistons and 12 spark plugs (which "ignite" on each cycle pump).

You can buy your own Origami V-12 engine online for about $110. The package includes, along with the paper, a PDF with 575 pages of detailed, picture-filled instructions. You will also need white glue and a sharp knife with a comfortable handle, for precise maneuvering." -http://blog.wired.com/gadgets/2008/06/the-amazing-ori.html

All I can say is "WOW!"
