“It took approximately two years to design this spectacular magical art for you to put together. This “V12 four-stroke Engine” has semi-realistic exterior and interior detail. Each of 12 spark plugs (LEDs) is ignited accordingly to the moving cycle. Many moveable parts include a compound crankshaft, a rapid cooling fan, 12 rods and 12 pistons etc. It is made with paper entirely (except some little wood sticks, some tapes, 12 LEDs, some electrical wires, 12 switches, a resistor, a motor and a battery holder). The instruction included in this kit is a CD-ROM (a PDF file)contains easy-to follow diagrams and step-by-step instructions with more than a thousand detailed nice and clear pictures. All patterns are printed on high quality acid-free heavy paper, which can last for many years and will not turn brittle and yellow or fades with age. No paint applied. It looks pure and elegant. Various shadows created by different light sources make it look stunning. The origami-reinforced structure is applied in the engine (they will not be seen). The origami-reinforced structures make the model very rigid and keep the pieces in the accurate positions.

A print-it-yourself version is also available. It is an identical kit as above mention except no paper (printed patterns) provided. It comes with a PDF file contains all patterns. You do the printing.
Both kits can be handcrafted with white glue and sharp knife etc.”
