*Math Stack* is a deck of playing cards with mathematical artwork on the faces. The makers call it “a potent and effective learning tool”. I’m not convinced about that, but they are so pretty!

*So pretty!*

It’s currently the subject of a crowdfunding campaign on Indiegogo, looking for \$2,000 USD. \$6 will get you a single deck of cards (plus \$8 for international shipping), or there are a variety of packages combining multiple decks, stickers, t-shirts and an e-book. Got to love those cheap Indian prices!

The team includes two PhD astrophysics students, an illustrator and sundry design types. Here’s a video showing off more of the cards, which are *so pretty*.

Each of the non-face cards features a different beautifully rendered mathematical constant, surrounded by some notation and descriptive text, and the Aces each have a different polar plot. You’re definitely not going to *unlearn* maths playing with these cards. I bet they’d fascinate a keen child to no end.

The Indiegogo campaign ends in July, and they plan to deliver the finished product in October 2015.

tl;dr: *SO PRETTY*

Thanks for featuring Math Stack in The Aperiodical :) We believe that churning up interest in a subject and keeping it alive is a fundamental aspect of the learning process. We hope and wish that these cards help do that at the least for mathematics.

Worthless garbage that will never arrive in the post.
