I cannot begin to envision the ingenuity that was used to develop that display..... how long did it take, was it a team or a individual....and why?
Now I shall answer my own questions. Cai Quoqiang, a 27 year old Chinese artist made this display in tribute to his grandmother, who had just celebrated her 100th birthday. Interesting background. http://www.caiguoqiang.com/artists-bio . Be sure to click on his gallery....amazing and diverse work.
