Matthew D. Sallin wants to replace the family tree with the graphical radially-extending family hedge.
It's a combination between a social networking application (like Friendster) and a networking experiment using data visualization. It uses a "Hedge" metaphor rather then a tree metaphor: traditional family trees are vertically oriented, showing a direct line from your ancestors up to you in present day. Such trees are limited in scope because they only consider the direct bloodline that results in you, and siblings and their spouses and children are excluded from this view. Conversely, a family hedge is radially oriented, expanding in all directions. [Link]The result looks like a fun project for the kids, using just a few old CDs and some wire.
