Stake Family History Fair

We have an upcoming Family History Fair coming up and my ward is in charge of providing an arts and craft, or family search game booth. I really would like to have something that will spark the younger children's interest, while at the same time, honor the theme of "Bring Your Family" so when the guests come to our booth, they can be engaged in an activity they all will be interested in. I am looking for some ideas. I don't know if there is an app that you can take a picture and it might tell you who you resemble that is famous or something but any ideas would be greatly appreciated. Thank you
