I have tried many presentations and never found the right one. Arranging the sections in columns, in two dimensions like a spreadsheet, seemed to me to be a pleasant solution. You can zoom out to see the plan, zoom in to focus on a section. Maybe easier on a tablet by double-tapping. And it's readable on a smartphone. Less easy on a station with a large screen where the manipulations are to be done with the mouse. Sorry if it disrupts the reading.
That said, I suppose the (aesthetic) choice of white text on a dark background is not the best... What do you think of this one http://lambdaway.free.fr/lambdawalks/?view=sierpinsky_compar... ?
