The oculus design by 360 Architecture, with engineer Buro Happold, for the convertible roof of a $1.2-billion multipurpose stadium in Atlanta represents a radical departure from kinetic roofs of other sports facilities.

The stadium design also calls for a novel 58-ft-tall "halo" scoreboard hung from the rim of the opening. Construction of the 1.8-million-sq-ft facility for football's Atlanta Falcons began last month, by the Holder Hunt Russell Moody Joint Venture. After the 71,000-seat stadium opens in 2017, the nearby Georgia Dome will be razed.
