This weekend, the co-founder of OkCupid may tell you what your dating habits say about you, but he won’t tell you to go bat-watching in Central Park. That’s our job.
Time Lapse at Derek Eller Gallery (6 p.m., Friday, Free)
Get a cultured and wine-soaked start to your weekend with Time Lapse. Alyson Shotz uses metal pins and white thread, as well as her own crushed sculptures (dropped from various heights with varying degrees of force), to depict the movements of time and gravity.
Christian Rudder and Jesse Singal at Littlefield (6:30 p.m., Friday, $7)
In a certain light, would nuclear war be exciting? What are six things you can’t live without? See what your responses to these inquiries actually mean in the language of algorithm-based matchmaking. Christian Rudder, founder and President of OkCupid, talks data with Jesse Singal of New York magazine.
The Friday Night Dancetravaganza at Beauty Bar (11 p.m., Friday, Free)
Now, enough culture and data. Head over to Beauty Bar to dance to everything from Otis Redding to “Like a Prayer” with East Side Social Club’s self-proclaimed booty-shakin’ mix. But get there much earlier, Daylight Savings Cinderella: the famed $10 manicure and martini special only lasts until 11 p.m. (and there’s a line).
Saturday’s events are on the next page.
Open House New York at Various Locations (All-day, Saturday, Free)
In its 12th year of opening the doors of New York’s most storied and interesting architectural wonders, Open House New York 2014 includes tours of St. John the Divine, the Citi Bike warehouse, Grand Lodge of Masons, and the Greenpoint headquarters of Kickstarter, among many others.
New Yorker Festival Signings at McNally Jackson Books (12 p.m., Saturday, Free)
Moping about the $40 it takes to go to a New Yorker festival event, or the $350 it might take to see Edward Snowden on live video conference? You might as well get your copy of The Brief and Wondrous Life of Oscar Wao signed. Junot Diaz, Zadie Smith, Paul Theroux, Sam Lipsyte, and other literary lights sign books at Soho biblio-paradise McNally Jackson. Last but hardly least: Patti Smith signs copies of the Folio Society’s special edition of Wuthering Heights.
Bats at Central Park, Belvedere Castle (6 p.m., Saturday, Free)
Bats have gotten an unfair rep, mostly due to their fictional association with vampires, but our only flying mammal — flying squirrels only glide, technically — is vital to controlling insects, eating from 2,000 to 6,000 in just one night. (They actually eat their body weight every night; for humans, this would mean eating a stack of pizzas equaling their own height.) Tonight, the Organization for Bat Conservation is presenting Bats at Belvedere, a seminar with live bats at Belvedere Castle, teaching us all about our winged friends. Learn how to spot them in their natural habitats, plus some fascinating facts, such as the similarity between a bat’s wing structure and the human hand, and the typical lifespan of a bat, which ranges between 20 and 40 years. Come early and enjoy the views from the castle. — Allen Barra
Oumar Konate at Baby’s All Right (11:59 p.m., Saturday, $5)
This young Bamako guitarist takes the tradition of players like Ali Farka Touré and Amadou Bagayoko to a grittier place on his impressive new Addoh (“Tears”). Recorded during Mali’s 2012-13 political crisis, Konate sings for peace, tranquility, and the love of a good woman. Traditional instrumentalists and the Debo Band horn section, who may or may not be among tonight’s advertised “special guests,” accompany him. — Richard Gehr
Sunday’s events are on the next page.
EXPOSED at Sumo Gallery (11 a.m., Sunday, Free)
The BBC calls Mick Rock “the man who shot the ’70s,” and you can bet the first image that comes to mind when you think of Queen or David Bowie or Blondie or the Ramones was probably taken by him. You can confirm this by viewing this Tribeca exhibit of his work, which also features never-before-seen photos of today’s most recognizable celebrities, like Pharrell Williams and Lady Gaga.
Halloween Flea Market at the Morbid Anatomy Museum (12 p.m., Sunday, Free)
Build your own curiosity cabinet with the insect shadowboxes, mourning jewelry, Día De Los Muertos kitsch and not-that-curiously delicious chocolate you’ll find while browsing this delightfully bone-chilling market.
Art in Odd Places all along 14th Street (All day, Sunday, Free)
The Art in Odd Places festival’s theme this year is “free.” For free, you can eat handmade tostones that represent the struggles immigrants experienced as they settled in Alphabet City. For free, you can step into a confessional and absolve yourself of any cultural insensitivity you once enacted. For free, you can be served a Sabrett-style hot dog made of legislative documents. And for free, you can watch people perform the ultimate free activity: absolutely nothing.
