We have covered plenty of cool decks of cards here in the past. These 3D Metal Mechanized Playing Cards by Dale Mathis are quite special though. They transform into an artwork with functioning gears. You get stainless steel playing cards and can place the deck into a mechanical frame and flip a switch to get the deck to animate.
There are 4 mechanical frames and 3 deck design options for you to choose from. You can find out more on Indiegogo.
