Here's the before:
(basically some useless space next to the deck)And here's the after:
A treehouse, complete with slide! The kids are in heaven (and I kinda like it, too). There's nothing like laying in the treehouse, listening to the birds chirping, and staring up at this:

Jay designed and built the entire thing. I supervised. Actually, I helped quite a bit, mostly in the painting department, although I did have a few turns at the chop saw. (There is photographic proof, but I'll spare you.)
The kids are loving it! Now with outside toys, a trampoline, a hill, bikes, and a treehouse, they have no excuse to come inside on sunny days. Well, except to get a drink of water, and Jay took care of that, too:
He created homemade water fountain. He is one clever guy, I tell ya. When he told me he wanted to make a water fountain, I admit I was a little skeptical. But not only did he pull it off, he made it completely adorable. I think the kids aren't the only ones who will stay outdoors all summer!
Some more pictures, if you're so inclined:
