A major development which came to fruition in November 2005 was the $59M new Oklahoma History Center at the northeast corner of the State Capitol, moving from its former location south of state capitol, shown below (aside from the 1st 2 "vintage" pics which probably came from the Oklahoma Historical Center's website,
http://www.okhistory.org/ , I don't remember for sure), I took the other pics shown below in October 2006:
