Winding down...in style?

The first year out of college was great for that feeling-your-way-into-the-professional-world thing where you have no idea what's appropriate and what's not in a workplace and/or career -- so you base all your professional (or not-so-professional) moves on a) what you observe, b) advice you hear or c) total and complete guesses.

I have two more weeks left in my job (before focusing solely on relaxing and a part-time research assistantship until grad school starts in the fall), and options A-C aren't helping me figure out how to gracefully exit.

I'm not going to start anything new in the bottom of the ninth here. I have to wrap some stuff up, compile stuff that will be helpful for my successor (poor soul) and pack up my belongings. Fortunately or unfortunately, I'm well on my way on most of that. So here's my question:

What do I do for the next two weeks? I don't want to look like I've mentally checked out, but let's face it, recycling papers and taking down tacked-up things aren't exactly thrilling tasks. And I can only do so much of that. But can't really do anything new. And can't quite start online shoe shopping in broad daylight.

Any suggestions? Personal experiences? Anyone want to write The Goodbye Email to my coworkers for me? (I'm really dreading that one...)
