As a student, Chang was influenced by Chinese philosophy and the art movements of Dada and Surrealism. Chang likes to produce sculptures that express his ideas and also challenge the viewer. Chang is sometimes asked of his sculpture, ‘What was your inspiration?’ or simply ‘What is it?’ He prefers to let viewers make up their own minds.
Some of his sculptural objects have a basic function. For example the mirrors on display act as mirrors, but they do not give a true reflection.
Other sculptural pieces have no function at all, but show Chang’s exploration of structures, patterns and theories such as bubble formations, networks and opposing forces. He explores these using techniques, some based on oriental lacquer work, which he has developed over many years.
