Created by one of the world’s most influential architecture firms, AX lets you play with a range of 3D building models using augmented reality. No architecture skills needed, just a curiosity for design. Choose from projects like Rush University Medical Center or the Shanghai Natural History Museum. Or play with the concept for Chicago’s River Beech Tower. You can then alter a building’s scale and examine its outer structure, and share the results on social media. All buildings are by top-ranked firm Perkins+Will.
