estherh, we did that once using pictures of family members, one of the more talented among us scanned them in and made the board. Then we had hints. Like which one lives in California? Which one has the longest name? etc… The adults and kids really enjoyed.
My friend once took pictures, cut out the noses of diff family members attending the party and enlarged it. By the Chanukah party everyone had to guess whose nose was whose. She said it was a hit!!!
