Surely a physical binary 0 tree would be nothing? Do you get half the cards you were expecting?
Also, being a data structure deck, I hope you've organised the deck in some funky way to optimise finding a card.
Cool! I’ve had some ideas that would involve physical, printed cards, so I’d be curious to know how you went about sourcing card makers and choosing one. Thanks, and good luck to ya.
I absolutely adore this project. I can't wait to see how it grows :)
I want this now. Take my money!
But really, the cards looks so good, can't wait to gift them to a friend.
