Interesting to see what an impact even a small deviation from the straight and vertical achieves: these three are all on Avenida Paulista, a premium Sao Paulo address where architects are given presumably a little more leeway, not just a cost / return target.

This one off Paulista is hidden behind the rectangular, but its curve stands out

Curving up and away from Paulista, it has banks, lawyers and airline tenants

All a long way from the view of this naive artist in the Museu Internacional do Arte Naif in Rio though; the vision is more like a scaled-up row of Greek villas. Will we be brave enough to move beyond the palette of sombre grey, beige and off-white in our corporate building? See http://brasilart.org/2012/07/19/trophy-towers/ for an example of one Brasileiro architect who has.
