What are some memorable activities from your wedding that people still talk about to this day?

Overwhelmed, but I want to make this a memorable experience. I saw a really cool idea on Tiktok where people downloaded some sort of photo or polaroid app, and they basically used the photos as a replacement for photographers because their friends already take good pictures. Personally, I am not sure if I want everyone's camera's out the whole time, but I like the concept and while it is my (okay our) day, I still want everyone to enjoy it. What are some cool ideas you have seen or done before?
