You may recall reading about Dash Snow and Dan Colen’s infamous “Hamster Nest,” a Dada-esque mass of shredded telephone books “installed” in hotel rooms around the world. Now's your chance to experience it firsthand: Ever the innovative patron, Jeffrey Deitch has turned his gallery over to the two art-world misfits, allowing them (and some 300 friends and hangers-on) free reign to shred 2,000 New York City telephone books. Unruly? Yes. Wasteful? Maybe not — when was the last time anyone put an actual telephone book to good use? “Nest” is up at Deitch Projects through Friday.—Rachel Wolff
