The floor plan thumbnails only represent the position of objects, rather than their exact shapes. They do not include chairs or equipment such as bunsen burners, flasks etc. In most of the thumbnails the entrance's location is not indicated. My favourites are 21, 10 and 19. The widely known Bohr-Rutherford diagram of an atom was heavily influential on the layout of the majority of my thumbnails.
