This evening we are introducing a great idea for a gift, from US artist Bradley N. Litwin. These are available to purchase directly from his site – mechanicards
They come ready made (50 USD each, also available as do-it-yourself construction kits 40 USD each).
MechaniCards are miniature, hand-operated, kinetic sculptures, designed and produced in limited edition, (numbered and signed by the artist). The handmade cards are constructed primarily from paperboard, with a few bits of wood, metal, or plastic. They are suitable for mailing, as truly unique greeting cards, and each piece comes with complete instructions and display recommendations.
There are five designs in the range and the first two are The Radial Engine and The Ambigulator.
The Radial Engine features an operable cross-section demonstration of the crankshaft arrangement, found inside a seven-cylinder, radial engine, similar to those found in many propeller-driven aircraft. The Ambigulator features a hand-cranked optical effect, and a mechanism that asks more questions than it answers!
