Orlando has had a rough couple of weeks following a series of tragedies there which occurred within days of each other. In the wake of the Pulse Nightclub shooting, which left 49 people dead, a movement emerged to boost the city’s spirits and honor those lives that were lost: #KeepDancingOrlando.

The concept is similar to the ALS viral videos, which were everywhere in the summer of 2014. People are challenged to make a video of themselves dancing as a way to simultaneously boost spirits and raise awareness of and donations to the One Orlando Fund. That fund seeks to raise money in order to provide support to victims of the Pulse tragedy and their families.

The process is simple: you receive a challenge, make a video of yourself dancing to Whitney Houston’s song “I Wanna Dance With Somebody” and post it to social media, passing the challenge along to someone else.

When Orange County Sheriff Jerry L. Demings was challenged to participate in #KeepDancingOrlando, he involved hundreds of Orange County Sheriff’s Office employees, as well.

From there, the OCSO passed the challenge along to their partners at the Orange County Police Department, among others.

Dozens of videos are shared on the Keep Dancing, Orlando Facebook page. Some are from Orlando residents and businesses and others are from around the state and country. Some are filmed with cameras, some with phones, and others with drones. A broad range of people are getting involved. A quick scroll through their page shows hospital emergency personnel, small business owners, Medieval Times restaurant employees, athletes, and more. There’s even a video of corgis dancing.

The Pulse Nightclub shooting became the deadliest mass shooting in U.S. history after a lone gunman killed 49 people and injured another 53 inside the club on June 12, 2016.
