Produced at Puzzila.org using FamilySearch FamilyTree as the source of information. This is a great way to view descendancy, much like a fan chart, giving you a quick look at the whole. They do limit the number of generations to 7 due to the shear volume of descendants that generates.
Limitations include currently the inability to display children of single-parent families. Also, information on the living is limited to the security imposed by FamilyTree.
