Nothing tops getting a card from a loved one, except maybe getting a Topps, as none of your loved ones had 94 walks in 1986. Surprise your friends with something other than Keith Hernandez's mustached visage, with Mechnicards
From a kinetic automata (self-operating machines)-tinkering mad scientist, Mechnicards are cardboard/ wood / plastic/ metal giftables that arrive in padded envelopes and unfold into interactive, 3D, hand-operated machines (each with their own unique movement), also available as do-it-yourself kits "not for the squeamish", probably because they graphically illustrate how to do it
Models (all available individually or as a five-card subscription package) include
The Radial Engine
His first ever: an insider's view of a prop plane's 7-chamber motor with a crankshaft that spins and pumps each piston -- though not Ben Wallace, as any more and he'd explode
Looking like a darker Dr. Seuss illustration, the card's got a locomotive wheel propelling an optical filter up and down to flash "yes" and "no", though it apparently "asks more questions than it answers"...or does it?
This crank-powered joint employs a series of gears to move a spinning/strumming device up and down while hitting four different notes, meaning including the Green Day album as part of the gift is no longer necessary
The site's also full of non-envelope-able madness, including a rotating machine dubbed "The Sway of Public Opinion" with six metallic unicyclists -- perfect for the guy who likes things singular, but already has a full collection of John Kruk's.
