Check out this amazing video, made by booklovers at a bookstore in Toronto. It explains what the books do at night . . . . .
"After organizing our bookshelf almost a year ago (http://youtu.be/zhRT-PM7vpA), my wife and I decided to take it to the next level. We spent many sleepless nights moving, stacking, and animating books at Type bookstore in Toronto (883 Queen Street West, (416) 366-8973).
