This incredible machine was built by Robert M. Trammell Music Conservatory and the Sharon Wick School of Engineering at the University of Iowa. Amazingly, 97% of the machines components came from JOHN DEERE Industries and Irrigation Equipment of Bancroft, Iowa. It is now on display in the Matthew Gerhard Alumni Hall at the University and is already slated to be donated to the Smithsonian.作者: 老林 时间: 2-5-2012 20:21
