Reusing in a big way

Well, you guys know how I am about recycling and reusing.  I save jars.  I save bottles.  I save little pieces of wood.  Hey, you never know, right? Could come in handy somewhere, someday.  But what about big pieces of wood?? 

You know, like this:

That's a LOT of little pieces of wood all put together.  And you know how I am about that.  So, first we take that all apart and make some piles.

Like this:

And this:

And then we put it back together, like this:

Yeah, I did cheat a little here.  You'll notice the bench seat was already made.  But I DID add those sturdy, handy dandy heavy duty legs, so that's got to count for something.

And this:

Use your imagination a little here.  It's the skeleton of a compost bin.  OOOHHHH!!!  Reusing wood and then reusing food inside the reused wood bin!  That's like reusing squared!!!!  Double bonus!

Then, of course, we still have this pile:

It's a big pile.  The kids would like a tree house.  Luckily, though the wood looks like crap, it's actually pretty sturdy and can be reused safely for such a thing.  They were disappointed we didn't build it yesterday, but we're still in the planning stage.  We have no idea how to go about it.  Jeff sees it as a platform, going around the tree, with posts on the ground.  Beanie sees it as a platform in the tree, dependant on the tree to hold it off the ground.  We have no double trees to nest it in.  It's going in a single tree, no matter what.  (Engineer boy, have you got any ideas?  I'd be glad to listen.)

So that's that.  Reusing at it's best.  Can you do better?
