The title wilfully sets us off on the wrong foot, because Buckminster Fuller, the famous architect and cultural philosopher whose text was the inspiration of A Simple Case of Vision had an unusual eye disorder. He was four before they discovered that he was abnormally lont-sighted. He had therefore came to know the world as a vague collection of blotches. Glasses let him fill in the contours with previously unnecessary details. But he continued to think in generalities and broad gestures. Batsry visualises this positively dealt with handicap in various artistic ways using lines of text floating by and loosely framed shots which penetrate into the ourside world of the anonymous city. These isolated images follow each other with wipes, so that they can then be studied for careful examination as through binoculars. Colours prove to be things. The tape accompanies, comments upon and alters the experiences expressed in parallel, so that normal viewers lag behind briefly in confusion.
