This weekend, the rooftop at Union Market is going to be brimming with all things bingo, including artwork inspired by the classic board game and three rounds of a life-sized 75-person bingo game where the bingo chips are people.

The free events are part of Let’s Play, an interactive exhibition put on by D.C. artist and designer Maggie O’Neill, which she says is meant to allow people to experience her artwork on a different, more experiential level.

For the past two years, O’Neill has been hosting bingo brunches and parties with her friends. After each event, she collects the used bingo sheets. These sheets have become a key component of her artistic practice (she’s even made bingo leggings and a bingo beach towel) and are the backbone of much of the 30 pieces of artwork that will be available for purchase at the event. A portion of the proceeds will be donated to Children’s National Hospital, which also hosts bingo nights for the hospital’s patients.

O’Neill caught the bingo bug three years ago when she attended a bingo night hosted by the American Legion in Southeast. “It was really fascinating to me,” she says. “The different kinds of people playing—every walk of life, every age group. There was a palpable sense of joy and happiness in the room. The room wasn’t necessarily attractive, but what was happening in the room was.”

She was drawn the atmosphere of the room but also, to the bingo sheets themselves. She found herself graphically and aesthetically drawn to the sheets, their colors and designs. So, she started asking if she could collect the used bingo sheets. At the time, she says, she was thinking, “This would be an amazing wallpaper, this is an amazing fabric. The materiality of it … all of these people had put their hands on their sheets.”

O’Neill has been creating bingo art ever since and this weekend, she’s bringing that work to the public and creating a space for them to experience it, too. She says that the event isn’t just an opportunity to see her work in a 2-dimensional, static way—it’s an opportunity for people to really experience her work in its full color in a setting where the event space itself is an extension of the artwork.

The rooftop space at Union Market, where O’Neill’s exhibit will be held, has so far hosted the 2019 season of the Washington Kastles, D.C’s professional tennis team. But the way that the space is being used for O’Neill’s event seems to be a first.

For the event, the rooftop tennis court will be transformed into a brightly colored bingo board and the first 75 attendees will have a chance to play a life-sized bingo game, where they themselves are the bingo chips. There will also be smaller, normal-sized bingo sheets and chips available as well as other games and raffles. Plus, there will be live music from the jazz band Brass Connection, prizes for the game winners, and food and drink from spots like Taco Bamba and other market vendors available for purchase.

Who knows, maybe you’ll even find your soulmate at this weekend’s event. O’Neill says that she’s made lots of matches at her bingo events and notes that the nature of the game can sometimes create an atmosphere where people can really connect with one another. “No one is trying too hard. You can’t really be competitive at bingo. It’s fun but it’s really disarming and maybe that creates a space where people can get to know each other.”

Let’s Play will take place at the Union Market rooftop on Sunday from 6 p.m.-9 p.m.
