He famously had problems with wind: The Great Sail was placed in order to break up wind off the Charles, which (by Bernoulli effect) would lock the doors at the bottom of the Green Building.
The funny part was: The Hancock Tower on the other side of the Charles had pretty much the same problem, but was too tall for remediation-by-artwork. They had a devil of a time redoing the windows in that building.
Anyway: 66 was always my favorite. Living in EC, it was always fun to show visitors the sharp point of that building.

The legend about how the nearby Alexander Calder sculpture was placed to block the wind is apparently untrue, but the revolving doors on the ground level are very real.

But then with all the other construction in that area, including some very big buildings, Stata now gets almost lost amongst its various neighbors.
