Usually in theater, the visual repeats the verbal. The visual dwindles into decoration. But I think with my eyes. For me, the visual is not an afterthought, not an illustration of the text. If it says the same thing as the words, why look? The visual must be so compelling that a deaf man would sit though the performance fascinated.
