Via BoingBoing:
Seven years ago, Horace Burgess prayed and received divine inspiration. He says that God told him "If you build be a treehouse, I'll see that you never run out of material."
And so Horace started building... and building... and 15 years later, he's still going.
The tree house is now 97 feet tall, supported by a living 80-foot-tall white oak, with six other oaks for support. It currently has ten floors, and a belltower.
