One powerful technique for supporting creativity in design is analogy: drawing similarities between seemingly unrelated objects taken from different domain. A case study is presented in which fractal images serve as a source for novel crochet lace patterns. The human designer searches a potential design space by manipulating the parameters of fractal systems, and then translates portions of fractal forms to lacework. This approach to supporting innovation in design is compared with previous work based on formal modelling of the domain with generative grammars.
