The interaction of this computing platform with users in generating new batik motif is conducted in form of workshop involving nine senior high school students. Interestingly, we have found that students could be easily perceived whether computationally generative motif resulted by fractal-generating software is appropriate batik motif or not. The emergence patterns of batik design also have found when these motifs are painted to fabric material by using traditional batik process. The paper reports the evaluation of the workshop.
