This chapter recalls a collection of experimental results on reconfigurable topology networks of oscillators, with Chua's circuits as chaotic dynamical nodes. Collective behaviours arising from network node interactions, such as global synchronization, emergence of clusters, patterns and waves formation, have been observed in a setup expressly developed [1-7].
