In a show of support and solidarity, employees of Disney, Universal, SeaWorld and other Central Florida theme parks took to social media Sunday after the mass shooting at an Orlando nightclub.

Kevin O'Brien, a 27-year veteran of the theme park business, compiled photos from various show casts, performers and characters as they formed heart signs with their hands and arms.

O'Brien's post reads: "Keep them coming Disney! This is family. We are one, strong band of people. From entertainment, costuming, techs, attractions, merchandise, custodial, and all other depts. Show that there is love out there!"

"My friends are my family and a lot of them go to Pulse," O'Brien said via a Facebook message. "I'm here to just say that we are all thinking of friends and families and the love ones who were hit hard with this!"

Photos include the cast of "Festival of The Lion King" at Disney's Animal Kingdom, the Dr. Seuss characters at Universal's Islands of Adventure, pearl divers at SeaWorld Orlando and the cast of Celestina Warbeck and the Banshees at Universal's Wizarding World of Harry Potter - Diagon Alley, among others.

Other photos are pouring in as the Facebook post continues to spread. As of 6:30 p.m. Sunday, the post had been shared more than 3,500 times. Some of the latest entries include performers from Heartlake City at Legoland Florida and the employees of the Transformers: The Ride 3-D at Universal Orlando.

The show of support comes after the mass shooting at Pulse nightclub in downtown Orlando early Sunday morning that left at least 50 dead and dozens more injured. It is the largest mass shooting in U.S. history.

Support has poured in from around the world Sunday. Thousands went to local blood banks to donate, while people both locally and around the world have donated to a GoFundMe.com fundraising page set up by Equality Florida.
