"György Kepes has commented enthusiastically on the ‘magic rhythms emanating from this swaying, dancing steel trembling with life’, and he has also noted the sense of ‘an instant fellowship, a spontaneous celebration’ which is re-created in their presence. As he concludes: ‘Rhythm is friendship and in Tsai’s work there is friendship of light, sound and our own heart-beats.’"
