Family Tree

[russian_mafia_x]

My grandmother is turning 85 in a month, and I know she would love a family tree with pictures of everyone in her family as a present. She LOVES pictures and all the walls in her room are covered with them. The problem is, I'm not really sure how to execute this idea so it looks professional. I will have the whole thing framed and such, but I'm having trouble coming up with ideas for how to make the actual tree. Should I craft an actual tree and glue on pictures? Should I go for the geometric approach and just connect everyone with lines?

Please share any ideas you might have! Thanks!
