Pentagram Does It Like They Do on the Discovery Channel

“If you have been searching online in vain for the phrase ‘gay dolphin blow-hole sex,'” e-mails Michael Bierut, “We are pleased to provide an answer to your prayers.” That’s right, Pentagram is well, behind, the design of “The Sex Lives of Animals,” an exhibition-cum-“celebration of the diversity of animal sexual behavior” that is on view at New York’s Museum of Sex through next spring. Bierut and Jennifer Kinon took inspiration for the show’s organization from an old field guide found at a Brooklyn stoop sale.
