Playing cards are thought to have originated around the 14th century in Europe, but others say that they were invented in China and migrated to Europe. Either way, it’s a big part of human history and there are tons of decks out there to satisfy whatever strange iconography you have a taste for, from Posh to the rotationally symmetric to pop art decks.
Kikkerland has created their own optically-mesmerizing deck in their set of Pixel Playing cards. The pixelated design seems to be see-through, but it looks like they won’t give away your hand anytime in the near future. Put on your game face.
