The paper seeks to define the concept of plug-ins jungleas generative background in computational design for new forms of dynamic relationship between human and artificial creativity. This definition will be conducted through the use of theoretical references and practical case studies with the intent to show that the current evolution of a plug-ins jungle is affecting design results at all its scales– from product design to urban design – and at all its stages – from design conception to construction and fabrication. In the pasttwenty years, the creation of software applications during the design process has exponentially increased in every design-related disciple and the use of plug-ins is giving birth to a new algorithmic evolution of creativity. One of the most interesting examples regarding such matter corresponds to the graphical algorithmic editor Grasshopper and the generation of a series of animal-named plug-ins through which graphically editing the coding process. Grasshopper and its plug-ins represent the touchstone of the ongoing evolution of a new digital jungle in which new software applications are not only augmenting human creativity, but they are also generating new forms of artificial creativity in themselves. The evidence suggests that the increasing use and creation of software applications during the design process is giving birth to new forms of dynamic relationship between human and artificial intelligence, an inbuilt dynamism through which the human mind and the machine constantly interact with each other producing unexpected and emergent design results.
