This week Dallas’ Meyerson Hall – home to the Dallas Symphony – is going to be transformed into a giant billboard. The IM Pei-designed building will be bathed in projected-light advertisements for a car-maker and publisher. “The projections will emblazon the symphony hall’s north walls facing Woodall Rodgers Freeway with intricate, abstract designs reminiscent of computers, in a tribute to Bill Joy, Internet wizard, Sun Microsystems co-founder and another of the Audi 8.”
