1. Statues to tax guys! This one, to Quintino Sella, Minister of Finance for the new Republic, 1869-1873, statue in front of the Ministry of Finance in Rome...
(1. a.) complete with naked people at its base - I'm sure they're some kind of mythological figures who loved collecting taxes.
(One of our favorite tax man statues was featured in an earlier post here.)
2. Creative ways to advertise
3. Holes in the formidable Roman Aurelian walls or views through other Roman buildings that make one think of a James Turrell skyspace. (We've also found those elsewhere in Rome, here, and here.)
4. Weird exhibitions of ...well...in this case, Tupperware (with the theme of bringing color to a piazza near you).
