During the three-day workshop hosted by the Gray Center for Arts and Inquiry, architect Frank Gehry conducted a small workshop of his own with collaborators from the Chicago Symphony Orchestra, and students from the University of Chicago.  Gehry designed the rolling projection screens that were ultimately used in the CSO's presentation of Boulez at 90: Provisionally Definitive, and this workshop provided him with the opporutinity to see how his designs were being put into action.
