Silk pavilion by MIT’s Mediated Matter group Silk producers cannot live in the wild after centuries of domestication and have lost (shed?) their ability to fly. Wild silkworm moths can fly, but their silk’s quality is much less desirable to humans.
Silk caterpillars do not display apparent remarkable group behaviours (due to domestication?) and individually spin the cocoons.
“3-D printed” using 6,500 live silkworms. Started with experiments to see if the spinning patterns of the silkworms could be controlled by altering the environment which they operated in. An aluminium scaffold was constructed and a CNC robot was used to string a lattice of silk starter threads across it in patterns to provide a base for the worms to operate. The aluminium and string frame was hung in an atrium at MIT and the silkworms were released on it .

However... Initially, some degree of self-organization or self-assembly occurs in the silk as a result of protein- protein interactions among the crystalline repeats in the protein chains, driven by both hydrophobic interactions and hydrogen bonding.
The density of the strings on the scaffold determined the opacity of a given panel. The output can’t be fully controlled, but the emergent (?) behaviour of the worms can lead to unexpected textures and features that would be impossible to plan.

This fast-paced extracurricular workshop studied elastic fabrics' ability to portray and engage the phenomenon of emergent, self-organizing and unpredictable form. It was essential to understand emergence as the natural, decentralized, non-hierarchical phenomenon of self-organization of form as yielded by the development of manual algorithms and logical processes via analog computation, and as influenced by material properties, context and other factors. MITâ&#x20AC;&#x2122;s silkworm pavilion experiment, a precedent which stimulated questions on the parameters of emergence, is a peculiar case study where natural agents that don't seem to display the survival-guided social behaviors of animal groups -such as the ant colony- create emergent complex form when introduced to a man-made medium. Initially, the experiment aimed to allow free agents to determine the fabrics' points of attachment, hence allowing form-making though a bottom-to-top approach, and starting with self-organizing, basic, independent and computational agents working together in a decentralized fashion. Live silkworms were introduced to the study aiming for this approach, resulting in a system that expresses the juxtaposition of the form made by the agent -as shaped by its natural, goal-oriented reasons- with elastic fabric media. The silkworm (bombix mori) does constructs more flexible in form under different spatial conditions not limited to two-dimensional or planar designs (more so than the spider, for example) The fabric media was initially meant to be interposed after the agent acted. Ultimately, however, experimenting with digital representations of algorithmic functions of natural growth determined the attachment points of the fabrics, and hence, their forms, after which, the agents were placed to observe their constructs. The fabric, thread and wood media, or HUBs (hybridity | unfoldings | bluntings) required parameters which would determine some of the agents behaviors (i.e. discouraging corner weaving), undermining totally decentralized emergence. Differing from the silk pavilion, the experiment was not attempt to express future possible material applications, but to express possible organic interactions between parameters of emergent form-making and man-made materials. The juxtaposition of and the interactions between natural and artificial elastic fibers was secondary. The results were organic, with most agents successfully completing their life cycles after spinning on both intended and unintended surfaces. Limitations were observed in controlling the agentsâ&#x20AC;&#x2122; spinning behaviors, but closely observing patterns, and opening questions about further media and the wide range of possible unpredictable results, as well as about the feedback of natural systems on artificial ones became a tangible source of interest. This is a system with potential for complexity and further experimentation, and despite not fully achieving a bottom to top approach, it offers a close look at the influence of constructed spaces on natural behaviors.
