I ran across this website that contains a huuuuge panoramic view of Paris that I thought you all might enjoy playing with.  As a warning, the website immediately starts playing rather loud accordion music.  However, this isn’t too far off from the true Parisian experience – after around ten in the morning the odds are favorable that any RER car you get on will contain at least one underemployed accordion player.  There’s probably a good Fermi problem associated with the number of underemployed accordion players in Paris.  Anyone care to try their hand at it?
