I am a super-organizer/cleaner. My mentor teacher...not so much.

But hey, he's been in the same classroom for decades.
New classrooms should be designed with shelves that fold in and out with the push of a button. Between all the talent on this forum, we should be able to find a designer and someone to actually build them, then we can patent it and improve the lives of teachers everywhere!
What is the best organization scheme/strategy you have seen in a classroom? I'm in science, so I'm particularly interested in labs...
