Gender Reveals that aren’t colour related?

My mom is colour blind and is also visually impaired so I would like to do something that she can enjoy as well. My husband and I are going to find out the gender but are thinking of doing something to tell our families. It would need to be something not colour related and big enough that my mom is able to see it at the same time as everyone else since her vision is not very clear. Any ideas? ❤️
