these playing card designed by Tauba Auerbach. Produced by DZEK in a hand-numbered edition of 250, each deck comes with the four familiar suits replaced by mathematical symbols and random shapes—as if, with Grandma beating you so soundly at Go Fish, you didn’t have enough to confuse you. This may be one of the last times you can get Tauba on a small scale as she’s just been named a participant in the 2010 Whitney Biennial, always a game-changer. $175 at No. 8b, 38 Orchard, 212-925-5599.
