Calling it a “living educational tool featuring architecture inspired by nature and science,” Pritzker Prize Laureate Thom Mayne and leaders from the Museum of Nature & Science today unveiled the schematic renderings and building model for the Perot Museum of Nature & Science at Victory Park. Groundbreaking on the approximately $185-million facility will be held later this fall, and the Museum (natureandscience.org) is expected to open by early 2013.
