How cool are these!
Read about Ursus Werhli's The Art of Cleanup here: http://www.brainpickings.org/index.php/2013/03/28/the-art-of-cleanup-ursus-wehrli/
While you're at it, you should also check out Amy's Poehler's Smart Girls (which is where I came across the above). I've known about this project of Ms. Poehler's for a while, but only recently Liked (capital L because this is serious business) it on FB (capital letters because OK I'm done here). These folks are constantly sharing great stuff! Have fun!
