Insektroniken are simple electronic circuits that mimic the swarming intelligence of insects. They activate one another by fast light flashes and buzzing sounds. This results in a communicative chain reaction that gets stimulated by darkness and inhibited by light.
It creates a network of vivacious communication even over long distances, like a hive mind. Due to their simplistic nature, it requires little effort and very low-cost components to produce new entities. Ultimately, their parasitic presence will analogously occupy niches and conquer surrounding spaces.
