The Different Deck
At first sight the Different Deck is a standard deck of 54 playing cards with one major difference - each card is inverted so instead of a 3 of clubs, you have a club of 3s.
Instead of a 5 of diamonds, it is a diamond made up of 5s and so on.
Each card is a unique piece of art filled with symbolism and hidden elements. If you look closely at the queen of spades you will see "queen" not only written in several languages, but you will find a queen chess piece and even a Queen Elizabeth signature.
Every dot, every swirl, every language, and every hidden item was placed where it was placed with thought and purpose. The more you look at a card and the more you look for hidden elements, the more you will find - things like ambigrams and words sharing letters, like the "T" in one word making an "X" in another.
There are over 100 different languages and numeric systems represented in this deck, plus there is symbolism and imagery in each card as well (an ant on a queen, or a toy jack on a jack, or an 8 ball on an 8, and so on). There are some really fun things in subjects ranging from science and math, to history and mythology.
