I was tasked with creating a special moment for our Good Friday service. We had people submit their names or the names of their family via our social media accounts. We then added those names to a cross. They started out as black and then were covered by red representing the blood of Christ, before they finally turned white representing our sins being washed away. Even though it's a little hard to see in this video you can catch if you look close. We also constructed a 14" cross, covered it with led tape and placed it behind the scrim so it wasn't visible until lit.
I've included a snippet of the original video below so you can see it better.
